for my science fair project, i tested fishing line. here are the results i got, i figured someone might find them useful/interesting. sorry everything's in metric, but that's the way science goes...also sorry for the crappy columns, but i just can't get them straight, but i think you can figure it out

*note, the breaking strength might be a little lower than the actual breaking strength because the down pressure from the hose was not accounted for.

**For Each Chart, in order from left to right, the lines go: P-Line CXX, Spiderwire XXX Super Mono, Berkley Trilene XL, Stren Original, Shakespeare Outcast, all 10lb test.

Breaking Strength (kg):

Trial 1      8.36      2.93      3.84      4.94      4.53

Trial 2      8.97      3.38      3.21      6.22      3.98

Trial 3      8.16      4.59      4.49      5.56      4.63

Trial 4      8.21      4.64      3.10      5.35      2.98

Trial 5      8.66      3.88      3.09      5.76      4.13

Avg.      8.47      3.88      3.55      5.57      4.05

A section of 4.5 kg (10 lb) test line with a loop at the end was hanging down from a support. A bucket was hanging from the loop in the line. The bucket was slowly filled with water until the line supporting it snapped. When the line snapped, the bucket full of water was weighed on an accurate, hanging scale. The breaking weight was recorded.

Abrasion Resistance (numer of cycles):

Trial 1      7      3      1      9      4

Trial 2      8      3      2      11      3

Trial 3      9      3      2      11      3

Trial 4      9      2      4      9      3

Trial 5      8      3      4      12      3

Avg.      8      3      3      10      3

A section of 4.5 kg (10 lb) test line with a 1.36 kg (3 lb) weight on the end was repeatedly pulled across a round pipe covered in 130 grit sandpaper at a constant slope of 45°. One cycle consisted of the line being slid down the sandpaper 7.6 cm (3), and up the sandpaper 7.6 cm (3). The number of cycles was recorded.

That science fair project looks very familiar. lol

Great experiment and information!  Thanks for sharing the results

Thanks man. That confirms a couple of theroies I had. Have you thought of testing knot strength? I saw that a few years ago on a fishing show. that would be interesting.

You should also add in line diameter.  Different manufacturers call differing line diameters "10lb" test.

Do you have that info for those you tested?
