Hide is beyond tough for sure, and they are a blast on fly rods. Carolyn looks at me madly at times, when I sneak the 4 weight back into her hand instead of the 6 weight... she says takes way to long to wear one out... I say have fun!
Just as a suggestion... fish intended to be released are a lot more delicate than many believe. Lots of folks would give a serious ass-chewing for over-working a salmon. An 8wt is more in line with what a chum deserves. As a guide it becomes more important.
