I suggest two baits. A Ned Rig (Zman TRD) and an in-line spinner (Mepp, Rooster Tail etc.) Both will catch bass and other species. A good retrieve for a ned rig is a extremely slow straight retrieve on the bottom. Another one is to drag the bait on the bottom with an occasional small hop. Colors would be dark green (green pumpkin) or black (black blue fleck). An inline spinner is the easiest lure to use. A moderate or fast straight retrieve is best. Let the blade do its magic. Colors would be a brown or black body with silver or gold blades. Both of these baits are easy to use and combine to cover the whole water column
