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.
