Greetings all!

I've been a ghost on the boards for a few years and have just now found a way to become active (my only previous access was at work--I could read but not respond). My usual passion is bluegills and redears, but lately I've been trying to target catfish on a fly. I've picked up several on accident fishing for bass with wooly buggers and crayfish patterns, and on summer evenings I've caught them on hoppers around moss beds and emergent weeds close to shore in farm ponds. Little brown cork "pellet poppers" seem to work around feeders. But here's the question for y'all: Anybody know any flies and/or techniques to consistently target these guys specifically? They are a load of fun and I'd love to find a consistent way to catch them!
