I dont generally target panfish, but based on incidental catches of them and observation, id say you cant go wrong with some size 10-12ish soft hackle wet flies that match the local forage, brown/black as a universal color. for topwater action, small poppers, terrestrials, and bushy dry flies produce good action. They seem to like a bit of commotion, so tie the hackles of the dry flies long and thick, parachute patterns get my vote in this category. short shank hooks on these patterns increases hook ups, in my experience. likely because of mouth size of most panfish. (small). Other than my preference for streamers, this is a nearly-identical fly selection that i get good success with, when fishing for yellow perch. (as for streamers, no perch can pass up a crayfish colored wooly bugger) Hope this is of some help to ya!
