Calcutta baits will work just as well but you need to get the jig/rubbah to the bottom to catch fish and a 2.5oz-3oz rubbah just wont cut it (in certain locations). I was tossing a 4oz jig the other night and it did not make it to the bottom....slapped on a 6oz rubbah and it made it. My shoulders were burning by the end of the night.
