I use 1/16 with plastic like BG's or something similar for just about everything. If I find a school deep or if I'm trolling I'll go to 1/8th. If I'm shooting shallow docks, I'll use a 1/32 with white or chartreuse bucktail instead of 1/32 with plastic. They seem to shoot better. Less wind resistance with the wet bucktail I suppose. It works for me.
