As a boy I used to tie just about everything. I was hoping to start back in again this winter but I just don't have the time. I still make/tie walleye/pike jigs.
I tied flies semi-professionally for a while. My favorites were clousers, because I could crank out 5-6 dozen in a hurry. But for my own use, a size 10 bead head wooly buggy, olive. Catches anything that swims. Or maybe some other fly I invented (I think). it's palmered ostrich hearl with a very light collar of marabou, extending back past the bend. I hove other secret flies I've designed, their killer and really simple, but your gonna have to come with a decent trade for those (small bowfin?)
