Douglas,
I have always used mono for leader line. It's tough and abrasion resistant which is important in the extremely rocky water I fish. Fluoro is supposed to be more invisible but cats are generally not line shy.
I mostly use 50 lb mono and occasionally heavier if I'm targeting monsters. If one is fishing muddy bottoms I'm sure 30lb would be great.
Hopefully the more experienced fellows on here will offer more help.
