I got one of these a while back Paul, though have yet to use it more than a couple of casts to look at what it does in the water. I bought it for the deeper body, as something a bit different from the thin minnow type lures. It should put out a different frequency due to the larger body.
Its my resolution to stop buying slight variations of the same lures, ie slim profile shallow diving minnows. Fat bodies etc are the way forward!
