Right now I use straight Braid for Punching, some top water, buzz baits, spinnerbaits, A rigs, and chatter baits.
Mono for crankbaits, some top water, and floating jerk baits.
Floro for jigs, swimbaits, and T rigs.
Braid to leader at times for everything.
Ask the same question next week and I'm sure I will have changed my opinion. Line is one aspect of fishing I always have very strong opinions about, but have been known to reverse my opinion often. Both braid and florocarbon have made me a hypocrite more than once.
If there were only one type of line, I would choose mono, or copolymer.
