Default line stretch

This is from last year but interesting none the less

Posted March 23, 2016

The last couple of years I have conducted a stretch test of a variety of fishing lines. I have now tested 20 lines – mono, co-polymer and fluorocarbon. My initial hope was to go beyond line manufacturer’s claims of “low stretch” because I found it varied greatly, and find out for myself.
I’m just an amateur and not affiliated or sponsored by anyone, but this was an interesting exercise for me. It will influence what products I buy going forward.
Like anything in fishing, I don’t think any single product will work all the time. I mostly use braid as a main line but usually tie on a leader for low visibility and abrasion resistance. In these situations I may actually opt for a leader material with more stretch to offset some of the no-stretch characteristics of braid. Other times, like when casting crank baits, I want a line with some give so I don’t tear the trebles out of the fish’s mouth. But then again, I don’t want a long hook set with a line that stretches like a rubber band either…
I hope you find the results as interesting as I did, it was kind of a fun way to kill some cabin fever the past couple years… -Fry
Here are the results, the primary update this year was selecting certain lines to be tested wet vs. dry ~
LINE STRETCH TEST

I used a 12 foot piece of each line and hung an 8 pound weight to see how much each line stretched in inches. Below are the results - least stretch to most stretch.

All Lines 8 lb Test Lines
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**


”Wet vs. Dry”
The above line stretch test was conducted with dry lines, which raises the question of whether mono, co-polymer and fluorocarbon lines stretch differently when wet? Two lines in each category were soaked for 24 hours and re-tested. Results were as follows:

Fluorocarbon lines
Sunline Sniper: dry 26 1/2 inches vs. wet at 27 1/8.
Berkley 100% fluorocarbon: dry 38 3/8 inches vs. wet at 39 inches.

Co-Polymer lines
Yo-Zuri Hybrid: dry 22 1/8 vs. wet at 25 1/4
P-Line CX Premium: 23 1/2 vs. wet at 35 1/8

Mono
Trilene XT: dry 21 1/4 vs. wet at 28 7/8
Trilene XL: dry 24 3/4 vs. wet at 36 1/2


Overall observations
*Newer Co-polymer lines being marketed specifically as “low stretch” for the most part seem to be accurate (when tested dry).

*Fluorocarbon tends to be the line with most stretch.

*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 (when tested dry).

*Mono and Co-polymer lines tend to stretch more when wet vs. dry. Most “catch up” to fluorocarbon in terms of overall stretch, however one co-polymer (Yo-zuri Hybrid) tested lower than any fluorocarbon either wet or dry.

*Fluorocarbon lines tend to break easier when stretched to their maximum breaking strength.

I've seen this online before and found the information interesting and surprising, especially the amount of stretch on the floura carbon lines.
However, I've been just as curious as to amount of hook setting pressure is applied in relation to line stretch.

Default line stretch

Good read ,think i came across this once before . also how long it takes for mono to break down in the enviornment like 600 years and alot lot more for flouro .

That is what is missing in his analysis. What you really need to know is the shape of the stress/strain curve (known as the Modulus of Elasticity or Young's Modulus) to determine where that stretch is taking place. When setting the hook with 8 pound test fishing line on an average fish I doubt you are putting anywhere near 8 lbs of tensile load on the line. If it were possible to measure the amount of stress put on the line in a typical hook set then test each line under that load it would be a more useful indicator of line stretch in a fishing situation. You could have two fishing lines that stretch the same amount as they near their ultimate load but one of the line's stretch could be close to zero when the stress of a typical hook set is placed on it while the other could stretch considerably. Kudos however to the person that did the testing in testing the lines wet. As shown in his results the properties of the different lines can change when wet vs dry. There are also other factors to consider besides line stretch when it comes to hook set. Especially in a trolling situation the line diameter and resistance as its pulls through the water as well as line buoyancy will affect how straight of a line the connection is between your rod tip and the bait. A buoyant larger diameter line will have more slack in it that will have to be taken up when you set the hook before the force of your hook set reaches the fish.

There is a great amount of technical information available and the testing and scientific knowledge exhibited here in this post. Kudos for the effort and knowledge. There are still many other factors involved in line choice. Equipment
starting with both rod and reel. Size and type of reel, rod action and length. type of presentation. Bottom type(rock'sand ,zebra mussles). And I think the most important, the angler. All these things come into play for choosing a line. It is a very individual choice in my opinion. Unfortunately a computer can't decide for us. And the line merchants give us so many choices it is daunting. I try a couple new lines every season, but there are rare exceptions when one tops what I have already found to be best for me. It is still one of life's decisions best made by the individual. Bob
