Drew the reason you are breaking fish off is your knot not your line. Fluorocarbon is much more abrasion resistance than mono and has more sensitivity.I like carbon pro the best. It last me longer but pline is good just a little more memory I just whish I could get carbon pro in 25lb test for flipping the bushes at Barkley lake.when you compare line strenth go by Dia. size instead of lb size then you will see the difference and which line is stronger.
