Try the C rig in these places (try to find the ledge):

Mouth of Buzzard Rock
Around the island on the main lake near Buzzard
Entrance to Kuttawa Harbor
Pump house and boat ramp by prison
Mouth of bay between buzzard and Kuttawa (road bed)

These are community holes, but a great way to get started. Once you locate the fish in these spots, and figure out what they want, start looking for similar stuff nearby.

There's an old railroad bed in buzzard rock marina, but I it's hard to explain how to locate it. It's about two cast lengths from the fueldock. Also the boat ramp by the restaurant is a great drop normaly holding very nice spotted bass.

Try a DT16 as well once you've located the structure with the C rig
