Have you tried the Rage Rig yet?
If I can't get anything to commit to jig, I will take a Rage Craw on a Moaner Stroker 1/4oz 4/0 hook and pitch it into cover. The slow fall with the action of the claws, usually brings out a strike or two. I'll also try a tube. My thought is, if they aren't hitting a jig, craw or tube, the fish aren't there.
