Stinkbait,
You might be right. Linder's show had underwater shots of him dropping the jigging rap onto the sandy bottom and then sweeping it forward with a lift. I never saw the rap circle back like it does normally when I ice fish it.
Back when Bob's Bait was open in GB he told me that if the current got too strong for a jigging rap to work well to put a small whole minnow nose hooked on the single hook on the back of the rap to stablize it. He said it was like putting a tail on a kite.
