Alumacraft Ducker. 64 lbs and slides over cattails and bulrushes like a dream and floats in 4" of water. See recent thread on Photobucket.

Tundras usually run 16-18 lbs. Meat is far better than any goose.
Much harder to bag one around here these days as our lakes got too deep and destroyed their traditional food supply....tubers of sago pondweed. Easy to kill because of that long neck. Just one pellet there is all it takes. I use 1's to increase the odds. Very easy to decoy. Do not try to pluck!
