At newburgh dam we use 1" white curly tail grubs. Tie 3 to 5 on about 12" apart. We also leave 12" of empty line at the end. That way we can use small weights if they are down a bit. You can also buy something called a sabiki rig from any catalog like bass pro. They look like 1" flies with about 5 to 8 tied on. Honestly go with the 1" grubs. That way you can change colors and replace damaged ones. Use a small jig head for crappie as your hook.
