whats a snarro? is that the deal with the clover leaf wires? If so I had a couple of them for qual, they seemed to add a bit of drag but shot pretty close. For archery duck and goose I used a broadhead backed up with turkey grabbers behind them. Can't remember what they are called but basically a washer with snag points cut into them.
Iceman the arrows will float, at least aluminum will, I asume the same for carbon and wood. For added flotation I rubber cemented the small hole in the insert to make them waterproof. Keeps a airpocket inside the arrow. Archery duck and goose hunting is a kick, my kill count went way way down when I used to do it, but each bird you got was that much better.
