I caught them until I got tired of catching them at the HRBT last year. I also caught qutie a few in Owls Creek. The best luck I had was using a double dropper technique with the fly rod. Tie a polymer knot to the first fly(heavy clouser) and the tie a streamer or deceiver type fly about 8 to 10 inches behind it. The first fly will contact bottom and the second fly will suspend just off the bottom. However, I caught most of mine on the fall and caught many on both flies. Sometimes I would even catch them on both flies at the same time. Two good size croakers at the same time on a fly rod put up a good fight. I used an intermediate line, long leader and a heavy fly, but I am sure you could use a heavy sinking line and a light fly and do the same. Olive, tan and brown worked well. I didn't catch anything on yellow or chartruese.
CPR,
