My partner and I have been using Gamakatsu line with very satisfactory results. We use 14# for our Steelhead rigs, 25# for Salt Mooching and 30# for Salt Trolling.
We were looking at line diameter; 14# is the diameter of Maxima 12#, so we figured we could get more length of higher tensile strength on a given spool. We thought we'd give it a try for starters, and have no complaints so far.
We're impressed w/ diameter, abrasion resistance, & Stretch. We've had no problems w/ knot strength.
A tad more expensive, but worth it.
For what it's worth, my brother landed a 63.5 lb HOG on the Skeena last year using 25 lb Izor line. Even though it took him 2+ hrs, its still a good testimonial for the line. Next time maybe he'll learn to hookem in the mouth.
