Fished with Invisx and didn't like it because on more than one occasion my crank bait went flying when the line snapped above my knot. I use the polomar knot. Fished with a guy this weekend that was using the same in 15lb and he got way more bites on a weightless fluke than I did using mono but he also broke off on hook sets twice. Anyone figured out the brand to use in the 15-20lb range that will work on cranks and plastics?
I have never had any problems with Invisx or the Red Label. (15 or 20). Vicious is good but slightly more stiffer and thicker diameter. I believe they "upgrade" the numbers. (Instead of 15 you actually have 17). I also use the Palomar Knot. Haven't had any problems with that either. BUT I do wet it when I tie it or it (or any line) will cause friction burn. Do not pull the two separate lines apart or it will kink the knot and cause it to weaken and break.
