Line Stretch Test - 18 Types/brands 2024
FryDog62 reply :
I bought into the fluorocarbon thing about 5 years ago in many respects because it is marketed as being "low stretch." I have a couple rods with no stretch braid, but also wanted to string up a few rods with straight fluorocarbon as a main line. I took a trip to Rainy Lake to target smallmouth. Lots of long casts, clear water, finesse plastics and spinnerbaits. Two of us in the boat, lots of fish and I had several long casts and hits. Whiff, whiff, whiff...
I usually don't miss that many fish. My fishing partner wasn't missing and he was having a good time letting me hear about it. So I switched back to braid on one pole and mono on the other...and started getting solid hook sets again. Made me wonder about how much stretch was in fluorocarbon.
Part of the reason I bought fluorocarbon was for its low stretch properties. Its no fun setting the hook with a rubber band. And yet that's what was happening to me. So, I decided to conduct my own independent test of 9 fluorocarbon lines versus 9 other mono or co-polymer lines. Many Fluorocarbon lines are specifically marketed as "low stretch." But compared to what? So, I decided to test them head-to-head in an effort to find out which lines truly were less stretch than the others.
My results are below. I used only 8 pound test lines in this experiment. You could do a number of different tests but the one I chose was to max the lines out and see how they stretched when pushed to their outer limits. I used a 12 foot length of line and hung an 8 pound weight from it. Lowered it slowly. Most lines would reach close to their maximum stretch after about 20-25 seconds, so at 30 seconds I took the measurement in inches. Results are listed from least stretch (in inches) to most stretch. I don't have a horse in this race and am not sponsored by anyone...just an amateur in pursuit of a good low stretch line:
All Lines Tested
- Trilene XT (Mono) 21-1/4 inches of stretch
- Yo-Zuri Hybrid (Co-polymer) 22-1/8
- Sufix Seige (Mono) 22-5/8
- P-Line CX Premium (Co-polymer) 23-1/2
- Maxima Treazure (Co-polymer) 24-1/2
- Trilene XL (Mono) 24-3/4
- Tectan Superior (Mono) 25-7/8
- Berkley Sensation (Mono) 26-1/8
- Sunline Sniper (Fluorocarbon) 26-1/2
- Gamma Touch (Fluorocarbon) 29-1/4
- Original Blue Stren (Mono) 29-3/4
- Gamma Edge (Fluorocarbon) 31-0**
- Bass Pro XPS (Fluorocarbon) 31-3/4*
- Stren 100% (Fluorocast) 31-3/4*
- Seaguar Tatsu (Fluorocarbon) 32-3/4
- P-Line 100% (Fluorocarbon) 33-0*
- Seaguar Invizx (Fluorocarbon) 36-0**
- Berkley 100% (Fluorocarbon) 38-3/8
*Line snapped once and was re-tested
** Line snapped twice - length estimated
Broken Down By Line Type
- 3 Co-polymer lines average stretch: 23.4 inches
- 6 Monofilament lines average stretch: 25.1 inches
- 9 fluorocarbon lines average stretch: 32.2 inches
Line Diameter
Line diameter can have an effect on stretch, but 9 of these lines all had the same diameter (.009 inches). Those lines are broken out below. The overall results are similar for the 3 different line types.
- P-Line CX Premium (Co-polymer) 23-1/2
- Maxima Treazure (Co-polymer) 24-1/2
- Tectan Superior (Mono) 25-7/8
- Berkley Sensation (Mono) 26-1/8
- Sunline Sniper (Fluorocarbon) 26-1/2
- Gamma Touch (Fluorocarbon) 29-1/4
- Bass Pro XPS (Fluorocarbon) 31-3/4*
- Seaguar Tatsu (Fluorocarbon) 32-3/4
- Seaguar Invizx (Fluorocarbon) 36-0**
Overall observations
- I had heard for years that Fluorocarbon line had less stretch than other lines, boy was I surprised with these results.
- Newer Co-polymer lines being marketed specifically as “low stretch” for the most part seem to be accurate.
- Monofilament tends to be somewhere in the middle, although those with a thicker diameter (i.e. Trilene XT .011 and Sufix Seige .010) did stretch less.
- Line diameter may have an effect on the stretch of certain lines, but overall, lines of the same diameter seem to reflect that Co-polymer and Monofilament lines still stretch less than Fluorocarbon.
- Fluorocarbon lines tend to break easier when stretched to their maximum breaking strength.
Curious to hear other people's feedback and if they have had similar experiences. -Fry

I've heard similar results (rip beat me too it). There is more to flouro and lines in general than its stretch. But it's still something to consider.
Makes me think of using 20 pound copoly for pitching rather than FC. Wonder how sunline reaction and shooter stack up.
Scott F reply :
Did you happen to look at the lines after they'd been stretched? Fluoro supposedly does dot return to it's original shape after it's been stretched. I'm curious as to your observations.

I did the read the entire article, I was also pretty surprised at the results back then. I agree though that the sensitivity of fluorocarbon is superior enough to mono/copoly that I will continue to use it.
curtis9 reply :
Interesting test.
Thornback reply :
Now I understand why I changed from flouro to braided 
David P reply :
Interesting review. Still some positives to fluorocarbon though. As mentioned, slack line sensitivity, as is the sinking quality, gets baits down deeper, and line visibility.
There's a time and a place for all lines, but certainly interesting to see that the marketed "low stretch" is not quite the case.
Smokinal reply :
I, too, just had to try the whole fluoro thing but also feel like I'm setting the hook with taffy. I've never missed/lost so many jig fish in my life. Went back to my braid = started sticking more fish. I may use fluoro on a treble hook bait but nothing that requires a hookset.
FryDog62 reply :
"Did you happen to look at the lines after they'd been stretched? Fluoro supposedly does dot return to it's original shape after it's been stretched. I'm curious as to your observations."
Yes I did check the lines over. 5 of the 9 fluorocarbon lines snapped and coiled up like slinkys. Even the lines that didn't break were coily. The mono/co-poly lines were a little stressed but pretty much back to their original shape.
FryDog62 reply :
I saw the Tackle Tour tests too - but wanted to conduct my own test with the type of lines I would use.
I honestly went into this hoping to find a low stretch fluorocarbon line, thinking there had to be some out there. I agree sometimes sink rate is preferred and flouro would win out there if I could find one that stretches less.
FryDog62 reply :
The one line I have used pretty extensively in this test is Yo-Zuri Hybrid. Very tough and abrasion resistant. If sink rate isn't a huge deal it is a great low stretch and very strong line.
If there was one line that stood out to me in this entire test though it was the P-Line CX Premium Co-Polymer. Not only was it low stretch, but it was much less in diameter than Yozuri Hybrid and Trilene XT (they are about .011) and CX is .009 (feels even thinner). I am looking forward to trying it out this year because I think it may offer at least some of the sensitivity of fluorocarbon.
There is no perfect line and various lines are good in different situations. I'm trying to experiment as much as I can and try some new things out. But honestly unless I do find a truly low-stretch fluorocarbon I'll probably stick with a co-poly of some kind.

The P-Line you call 'Low Stretch"? Compared to the other lines you tested it may have been low stretch, but that's like saying a Ferrari is cheap ......compared to a Lamborghini.
Montanaro reply :
Shooter tested as low stretch by TT. That and abrasion resistance makes it good for pitching.
I may have to revisit copoly though, just doubt it can top shooter for what I use it for.
Alonerankin2 reply :
Well I'm not surprised, I use FC on wacky rigs in 6 to 8#, open hook of course.. My long time standard lines are Yozuri & CXX and a bit of CX. I do not use braid. Interesting read, thanks for posting...
Grantman83 reply :
Slack line sensitivity and abrasion resistance are why I love Fluoro. I love sniper and invizx but it's obvious how much they give.
Shooter is the strongest and toughest I've used.
FryDog62 reply :
I think there are 3 versions of Shooter now - is it the "Marrionette" that stretches least?

Logan S reply :
Very cool post, thanks!
Does anyone else think that the rate of stretch may be different for each? I think that if you made a graph of stress vs stretch, mono would be linear and flouro would be exponential. I've always sort of felt this way based on my own personal experiences, but I've never put in the effort to test it like the OP has. Maybe a test with a 1 or 2 pound weight would show this?
To give one example of why I feel that way...Ripping traps through grass is much more efficient for me with flouro instead of mono, it feels as if the line stretches less - making it easier to rip or pop the bait through. However if you only look at the #'s in the OP's test it would seem to be the opposite. That's why I think that flouro stretches less at lower (more 'normal' for fishing) stresses. It 'catches-up' to mono in the amount of stretch as it gets closer to the breaking limit.
I could be wrong, it's really just guesses on my part...and it won't change my choices, but it is a cool winter topic .

Try Toray Super Hard Strong, very low stretch and very strong ...
Tim Kelly reply :
It's an interesting test, but I don't think it is as relevant for actual fishing simulations. What you're testing is the elastic limit (breaking point) pretty much. Fluoro seems to stretch until it fractures and when it gets near to it's fracturing point the line is very degraded. Mono tends to be able to stretch and bounce back much better. If you are pulling for a break you are aware of this, but when you're fishing the properties of FC and mono are very different. Fluoro feels much more direct. I would guess it resists stretching for longer than mono and when it starts to stretch it starts to get damaged. Mono doesn't resist stretching at all so you get a linear amount of stretching at all loads, which is why mono feels less connected.
K_Mac reply :
I also think the test is interesting, but it will not influence my use of fluorocarbon. I have done my own testing on the water and prefer the way fluorocarbon transfers vibration. I resisted the rush to fluoro and don't really care much about having the latest and greatest gear. I have tried most of the other lines; I will continue to use fluorocarbon.
thehooligan reply :
Pretty cool test. Surprised sufix did that well, i like there monos but it always seems like there line stretch alot.
Only fluoro i mess around with is sniper, and its a love/hate thing for me.
I like cxx, hybrid, maxima and floroclear so much that i rarely use anything else anymore.
smalljaw67 reply :
When I tried fluorocarbon, I tried it on a spinning reel and I hated it and had so many tangles that I didn't give it an honest try, it just was too unruly for me. So I tried it on my casting set up, well when I said that it seemed to stretch as much, if not more than my mono did, I was told it was old line or perhaps it wasn't stretching but just felt that way ,etc. etc. The line was Seaguar Carbon Pro and it was the last fluorocarbon I used, my buddy had me try his Tatsu on his rod and I told him after pulling on a snag that it stretched too, it just felt slightly different, he said it was my imagination and now I see it isn't just me. I fish heavy flipping and frogs with braid, I know when a line is stretching and when it isn't and fluoro doesn't feel the same as mono but it does stretch. Here is one thing I tell young anglers, try things and don't knock something until you tried it, for me fluorocarbons don't work, I don't feel I get any advantage using them and I don't feel disadvantage not using it. Some anglers like fluorocarbon, the sinking line may be better for them with wacky rigs or drop shots, you have to try it to see if the pros outweigh the cons.
Preytorien reply :
I use flouro for finesse soft plastics application....sometimes....otherwise it's straight braid for me all the time.
tomustang reply :
I knew a guy once that I showed this type of data to and he laughed at it and continued to believe what the product box said.
The initial stretch in the hands when first handling the line should show you enough elasticity compared to other lines you handled.
Turtle135 reply :
Thanks for conducting those tests and posting that information. I always like to hear the results from an individual who is not involved in promoting a particular product.
For what it is worth, on my baitcasting gear, I use 14 and 17 pound test Trilene XT for pitching and casting jigs. I know the 14 pound test breaks at around 20 pounds so to some degree I combat the stretch issue with mono by using heavier line. I find that line to be very abrasion resistant and very strong. Frequently I find myself straightening out a hook (instead of breaking off on a snag). I do most of my jig work at close range fishing from my kayak. I change my line frequently, usually at least once a month.
BrianinMD reply :
Interesting test but will it sway me at all away from straight flouro for almost everything I fish, not at all. These test may be interesting but the test I will follow every single time is results on the water. I switched to almost all flouro before last tourney season, Stratos20SS will attest to how well that went. I won 5 out of 8 tourneys, losing the last one by one ounce. Had big fish at a couple tourneys along with lunker of the year. These results mean way more to me than any of these tests.
The setups I do not have flouro on are top water and frog rods.
WIGuide reply :
Interesting study to say the least. I'd love to see a shock test though. One where the lines are not maxed out on what they're rated to handle, but rather with a smaller weight similar to the weight exerted by a hooksetr. It'd be interesting to see that data compared to overall stretch.
FrankW reply :
I read lots of forum members talking about slack line sensitivity with Fluro. I don't fish a lot of Fluro but I have never noticed that Fluro has any better slack line sensitivity than other lines. If I am not in contact with my bait then Fluro doesn't tell me anything more than what braid does. Has there ever been a slack line sensitivity test? I think that is a myth like the one that Fluro doesn't stretch as much as mono. A good deal of what some of us know comes from reading other peoples comments rather than personal experience or testing.

Master Bait'r reply :
See that's a cool test but an incomplete picture to say the least. You're measuring one specific parameter, and not even in the context of it's use. Nobody is using 8lb FC with the drag locked on a broomstick. The "results" you show, while being interesting, do not give us an accurate portrayal of when the line actually begins to break down. I'd love to see it redone with respect to the percentage of test rating applied and at what point does it stretch beyond rebound- not just "it stretched two feet & broke"
Cool test but it made me wonder even more tbh.

So then why dont you all conduct your own tests on the matter since you feel so strongly about it? With your own "parameters" and other hoy floy academic thinkin'.

No.
But if you're going to do it... Go all the way. Just saying- it certainly had an outcome, but what percentage of that outcome would be relevant in real world usage? Bringing a product to absolute limit begs the question why use that as a benchmark? I think OP is definitely onto something, but there are a lot of questions that taking the first step can create- such is scientific pursuit.

I believe what they are talking about is that you can detect a bass popping a jig or a plastic worm without having a tight line with flouro (or with mono). You can feel that vibration transmitted up the line. With braid if you line is "slack" much of that vibration can be absorbed and you may miss that "tick" traveling up your line.

Although this info is going on 8 years old, I still hear anglers touting fluoro for its reduced elasticity.
The reason that you cited for using fluorocarbon is probably the best reason (though line-watching achieves pretty much the same)

smalljaw67 reply :
The line is still dense and it still sinks, and even though I always knew it stretched, I didn't realize how much it did. Not only the OP's test but if you google it there have been a number of test done showing how much stretch is in fluorocarbon. If it works for you then great, I tried it and I didn't like it but it doesn't mean because it stretches it isn't any good, but a lot of anglers claimed that the near zero stretch is what made it better and that is just POS or power of suggestion.

If we go back to your original post in this thread you clearly imply that those of us who use fluorocarbon are simply fooled by the tackle manufacturers marketing. Also implied is your superiority in discerning such foolishness. Your criticism of others for relying on their own opinion seems a little hypocritical to me.
For the record I don't care what line anyone uses other than the people whose opinions I trust. This is a discussion forum though. Why is it we can't discuss these things without pettiness?

I enjoy catching fish, so naturally I wanted fluorocarbon to be everything it was cracked up to be (still got a drawer full of the stuff).
Over time however, I had to loosen my grip on whimsy, and tighten my grip on reality (there go my delusions of grandeur).
> Fluorocarbon is 'twice' the diameter of braid, but is not 'twice' as abrasion-resistant as braid.
> Fluoro is dense, but trollers & deep-sea fishermen usually achieve greater depth with 'finer line diameter' not "denser line"
> Fluoro fractures easily and thus has poor knot strength. The last 2 knot failures I had in many years was braid juxta fluoro
> I admit to being spoiled by braided polyethylene, and no longer have the tolerance to fish with an elastic band.
I've actually caught myself taking a step backward while setting the hook with Seaguar Tatsu fluoro (to absorb the elasticity).
Roger
WRB reply :
A few questions.
1. What knot did you use?
2. Why test stretch at line strength without using 75%* of line strength? 8 lb @ 6 lb load?
3. Did you measure the line? What with?
* it's impossible to apply 8 lbs load with tackle used to fish 8 lb line, 6 lbs is high enough to yield 8 lb line.
The lines should be grouped by diameter, 8 lbs label line with .009-.0095 only. Any line larger diamter like Yo-Zuri @ .011-.0115 should be at 12 lb test or 75% = 9 lb load.....apples. To apples. Yo-Zuri 4 lb test is .009, use that in your 8 lb category for example. Sunline and others 12 lb line is .011-.0115, use those to compare line in the .011 diamter class.
Your stretch test shows how honest line mfr's are, good post!

Eccs reply :
What I think this chart helps me with is it gives me a better idea of which fluorocarbon lines stretch the most. So in an application that you prefer mono for it's stretch you can get a line with high amount of stretch but also that sensitivity that fluoro is highly regarded for. Best of both worlds

If there was one line that stood out to me in this entire test though it was the P-Line CX Premium Co-Polymer. Not only was it low stretch, but it was much less in diameter than Yozuri Hybrid and Trilene XT (they are about .011) and CX is .009 (feels even thinner). I am looking forward to trying it out this year because I think it may offer at least some of the sensitivity of fluorocarbon.
I'm a big P-Line fan so I've been fishing CX on spinning gear for years. I've tried to tell people how good this line is but most guys simply won't try it because it isn't the "latest/greatest". About the only P-Line product that I've not liked is Fluoroclear. It has a ton of stretch and poor knot strength, or at least in my experience it's performed this way.

A few questions.
1. What knot did you use?
2. Why test stretch at line strength without using 75%* of line strength? 8 lb @ 6 lb load?
3. Did you measure the line? What with?
* it's impossible to apply 8 lbs load with tackle used to fish 8 lb line, 6 lbs is high enough to yield 8 lb line.
The lines should be grouped by diameter, 8 lbs label line with .009-.0095 only. Any line larger diamter like Yo-Zuri @ .011-.0115 should be at 12 lb test or 75% = 9 lb load.....apples. To apples. Yo-Zuri 4 lb test is .009, use that in your 8 lb category for example. Sunline and others 12 lb line is .011-.0115, use those to compare line in the .011 diamter class.
Your stretch test shows how honest line mfr's are, good post!

Tom, I'll try to answer most of your questions best I can:
1) I used a double Palomar knot. Where lines broke, it was up the line above the weight...the knots held.
2) I think there are a number of ways to do this test and I may do more. The reason I picked an 8 pound weight was to use the maximum so as to accentuate the difference between the various lines. Although a lesser weight might be closer to the real world, some of the results might be closer together and harder to see differences. We're all looking for subtle differences in the products we choose, and I wanted to try to make those differences as obvious as possible. If I get time, I may do another round of tests at 4 pounds on a cross section of these lines.
3) I measured the lines with - what else would a fisherman use - a Hawg trough... Ha! Of course I'm Kidding, I used a tape measured and tried to get down to 1/8 inch.
4) Yes, I do think that line diameter can make a difference in stretch - that's why I did the second breakout with just those that were .009 inches in diameter and throw out the Yo-Zuri's and XT's that were thicker. There were 9 lines (half of the lines tested) that fit the .009 criteria. But in terms of the 3 different line categories, fluorocarbon still stretched the most. P-line CX co-polymer and several of the fluorocarbons were the same diameter but CX stretched less - and maybe most importantly, didn't break.

Good stuff frydog62 - I've done a ton of line testing on my own also, so I can appreciate the effort and interest. Lots of ways to dissect the data and run the tests, all of which will give different results, but will also help answer one small part of the puzzle.
Another interesting test you might try, beside the 1/2 rated test (I've run it before and you should see some slight differences there), is to soak all lines in water for about 1 hour before testing to better simulate "field" conditions. This is important because nylon lines absorb water, and some tests show changes to stretch increase by as much as 20% or more (vs. dry) depending upon exact test. Theoretically, all 100% fluorocarbons shouldn't absorb water, and therefore, you shouldn't see any change in stretch between samples tested "dry" vs. samples tested "wet." My guess is that if you did this, you'd see a difference in results, with many of the monos and copolys stretching more than your original set of data, quite possibly more than the fluoros at that point.
Additionally, there is a pretty strong inverse correlation between line diameter and stretch, so the closer you can keep the lines paired and tested in that regard, the better the quality of your data.

Interesting test, thanks for posting!
primetime reply :
I have been having line debates for years especially when I worked in a tackle shop spooling line, and I can say with 100% confidence that Fluorine (which is fluorocarbon monofilament) stretches the most by far which your findings illustrated. The low stretch came as a gimmick early on when the lines were so stiff that you couldn't use it for main line like companies wanted so badly since braid improvements in last 15-20 years is amazing and companies realized that people would pay $15, and be good for 2 years and now they are not selling enough line..IN comes all the fancy copolys and Fluoros (Notice the Saltwater scene or magazines till this day are not pushing fluoro main lines, those guys use heavy Mono leader which is expensive so no need to push fluoro main line and then have issues of breakage and learning time with it, guys who fish saltwater heavy use fluoro for leader for abrasion resistance, other than that I don't think they care about clarity etc.
I use fluoro because I think it helps soft baits sink more naturally, is more stealth, thinner generally if good quality, but needs to be taken care of. I used to hate it but in the last few years, last 2 years it has gotten much better but it is a good shock absorber for braid, Mono is actually worse but nylon and copolys float since they really don't put much fluorine in copolys, it is about marketing money...Just watch Diameter, Breaking strength, and don't assume expensive line is better, only 3 factories if not 2 make pure fluorocarbon. The easier it casts the abrasion factor is less, but that is what leader is for, fluoro leader is stiffer than regular fluoro, that is something I would like to see tested, I can feel my baits better with fluoro to braid than Nylon mono to braid but maybe it's in my head?
Also, I used to like line conditioner for memory, but fluoro is waterproof and sunproof and bullet proof, so a guy from Lockheed martin who is a smart guy with all this stuff told me that it only works because I want it too, and sun tan lotion would do the same as line conditioner, it is only good for your reel and for seeling Nylon if you believe it does that. I can't find a reason to put in on Fluoro because the memory is reduced by pulling the line while applying it but that is deforming it and stretching it which reduces memory since we all know how easy fluoro is to handle on spinning gear...But I like it as a leader and main line, I am careful, tie often, and you kind of do get what you pay for...Seaguar and Japanese companies seem to be ahead in the fluorine market, Hybrid is great if you want clear or green wire, 6lb is 12.8 lb test but makes a heck of a flipping line, not ultra soft though.....
