Leader You should always use a leader of a lighter strength below your float so you don't lose your float when your lure breaks off. Leader length should be at least 18 inches to the swivel. All kinds of setups can be placed below the float. A jig can be used with bait and without. You can use a drift fishing rigging below a float using back pressure to fish tail outs or just to cover water that tends to be to snaggy to drift fish.
Soft plastics are also a favorite used on jigs and with out.
Soft plastics can be used in worm, egg cluster and single egg presentations. All of these methods can be combined in one way or another to meet almost any situation. Straight bait such as eggs, sand shrimp or night crawlers can be extremely effective when presented in the correct manner. In extremely clear water you may even give single eggs a try.
