Thats a loaded question, lol.
I typically use braid over any other line solely for how good it casts, line management, and sensitivity. Besides topwater, there are guys that crank with braid and also finesse fish.
Ive got it down to,
topwater/froggin - 30lb braid
crankin - 12lb mono
spinning finesse - 10lb braid/6lb flouro leader
baitcasting finesse - 6lb flouro/mono
