Looks like I'm a bit late, but I'll go ahead and jump in with my $0.02 worth. I fish PT Nymphs, Hare's Ears, etc., also, with a heavy helping of scud and freshwater shrimp patterns. I don't like to go smaller than #12's because of the problem of deep hooking with the smaller flies. Sometimes it's necessary to go to the smaller sizes, but it's a last resort for me.
