Chris,
I've been thinking alot about this also. In fact, I just recently bought some LedgeBuster spinnerbaits like the ones Darin mentioned. The main reason for my interest in them is that I know alot of nice bass are taken in winter on a slow rolled spinnerbait in deep water. I think the LedgeBuster's are going to be good, but i'm not going to stop there. For a while now i've been looking for twin or double armed spinnerbaits. These things are really hard to find! I've found one or two different brands that make them, but i'm not sure if it's excactly what I want. I'm going to keep looking and i've even started to mess around and come up with a prototype, but I haven't got to fish it yet. A slow rolled, twin armed spinnerbait fished in deep water is something that I bet few big bass have seen.
