Rankbull...I'm just getting started on this, but here are a couple of things..

Rather than suspending the bait just off bottom, I'm using small pieces of crawler, perhaps 1/3 of a worm, and letting it lay right on the bottom...That way the bottom feeders like the bullheads will still pick it up but you have less trouble with bait stealers like small sunfish and shiners..I've heard that some guys have had good results with pieces of raw cut shrimp, but I haven't tried it yet...

I've been fishing around midday...Caught 7 yesterday in about three hours from 11:00 to 2:00 PM...
