I assume you are talking about open water slabbing? Here in central Iowa we use a number of different kinds of slab spoons for white bass/wipers. Do It Molds JS-3-A is a great spoon and we use them in 5/8 to 1 3/8 oz. Long cast, let it hit bottom with quick jerks off bottom and then let it settle back to bottom. The shad spoon mold is also one we use (item #3482) in 3/4 to 1 1/2 oz. Fish the same way. We have caught whites/wipers, walleyes, crappies, and flatheads fishing these types of spoons. They are a blast to fish and you can cover alot of water.
