Sunline assassin fc review

I read about this new line from ICAST so I bought a spool of 20 lb to check it out. It casts like other fluorocarbon line but broke twice, once reeling in a fish and once inside the reel spool. I have always been an Invisx user and will continue to do so. Nothing about the new line impressed me enough to want to continue to experiment with it. I never break invisx.
