Many guides and fishermen I know and respect fish fluorocarbon. They believe the extra clarity of the line is worth the extra cost and the poor knot strength.
I respectfully disagree. I have used YoZuri Hybrid (not the newer softer H2O formula) for five or six years. The fluoro exterior and the copolymer interior means it does not sun age like mono, it ties like mono, it stretches only a little,and neither sinks nor floats. On top of all these qualities, it is cheap!
BTW, last year I tried a spool of Sunline's Super Natural mono. It was good stuff, but like a lot of Japanese lines, the break point is actually near the advertised strength. That explains why their 10# is only .10 inch diameter.
I generally wart and topwater with 10#. I jerk bait with 8#.
I have referred to the Tackle Tour tests on fluorocarbon before. Google it and read. Makes you quite a bit less sure about spending so much for fluorocarbon.
Just my opinion, and remember I did point out people I respect disagree with me.
