It usually involves a Lizard, but any bait can be used.
Color is unimportant.
Next add a Barrel swivel, and a leader line that is somewhat smaller than the main line. This rig allows the bait to get down quickly to the bottom in deep water areas, and can be worked relatively quickly. The heavy weight gives you a much better feel of the bottom. The leader allows the bait to swim and rise above the bottom, and fall slowly down. It works best in deep openwater areas, but can be used anywhere.
