I keep meaning to make a post on what I've been using. I bought a 12 foot telascoping crappie rod. Almost like a bamboo rod. I tied about 5 feet of 6x tippet to it. If they're not biting my fly. I suspend it just on the surface. My hands shake just enough to make surface ripples around it. Deadly! They will hit any fly that way. Otherwise, fly and bobble. I've hadf alot of succes w/ skud flys once they start to sink.
Slipfloat and a 1/32 or 1/64 tube(#1 red/white #2 chartruese) are killer. Twitch and let sink they smash it on the fall. For perch I use a steady slow retrieve and twitch. Float and fly is awsome with the right conditions and a light action 7" rod. Just keep the leader long(36-48")
