bassnbro is right just drop the jig all the way to the bottom and reel really REALLY slow. If you are using a spring indicator watch for it to bend ever so slighty and set the hook. Otherwise watch the tip of your pole and if it moves down in any amount and you feel a really light dead-weight feel set the hook. Blue/Green and Black/Red or Black/Orange are the go to colors, they have all 3 in 1/64 and 1/32 size at the lake office. I use mostly 1/64 oz. Try the 4 corners inside of the dock first, have had better luck in the corners this year. If the banana jigs aren't seeming to workout switch to a little 1/64 or 1/32 oz. hair jig or maribou and pitch it out, wait 5-10 seconds, and retrieve slowly. No particular color seems to do better than another for those, even though I did see gray work really well one day. I've used chartreuse and red and caught fish on both.

Sorry for the long reply, just thought I'd help out a little too. Good luck!
