I don't do it often but every once in a while (including this Saturday) I get out to a few feeders creeks with my 3wt fly rod and tie on a size 18-20 foam beetle or mayfly for 2-8" Cyprinids. Tight line size 16-20 nymph patterns for micro Suckers and Sculpins as well (Darters hit them, but their mouths aren't large enough even for size 20 hooks).
