Goose body and the MAGNUM Herters duck head...definatley worked for him and I can remember being 14 and wanting nothing more in the World than to have a rig like his and hunt where he was hunting.....
Never got the decoys but have hunted where he hunted and out of the boats he talked about, hunted out of and designed, plus others that he never talked about.....him and a writer who was a NJ who Game Warden and wrote incredible stories about Black Ducks, Barnegats and the now lost duck shacks in the Jersy marsh, whose name sadly escpes me, pretty much introduced me to hunting in other than aluminum jon boats......
I don't know about scaring Geese but a Swan decoys are KILLER for attracting Cans and Wigeon if they are using the same areas, just like Brant are better Pintail decoys that Pintail decoys...if you are thinking about Swans think about a life sized (3) bird Y board.....you'll be pleased....
