I Never use mono to much streach. I use 8 pound floro on my spinning for my super finesse -drop shot , split shot ect
I use 12-16 pound floro on a baitcaster for what I like to call heavy finesse- mostly jerbaits and some crank baits.
Braid on a baitcaster for heavy situations- frogs, jigs and whenever I'm pitching or flipping in cover.
