It depends on what fish you are aiming for and where you are fishing. If you are fishing for bass, then I wouldnt leave anything on the bottom. I would cast and reel. If you are fishing for cats, like with bluegill cut bait, I would use a hook on the end and three feet up a split shot, then up from that a 3/4 oz egg slip sinker. With that rig, the fish can get the bait and move with it before you set the hook. If you are in heavier current, just up the weight.
But in general, the Kankakee river for me is smallie country and I would spend the day casting rattle traps etc.
Do not tell fish stories where the people know you; but particularly, don't tell them where they know the fish. - Mark Twain
