Somehow, I think that when you are trying to fool a bird with a brain the size of half a walnut, that has basically monocular vision (no depeth perception) and is traveling by at 30 to 40 mph, you don't need that kind of realism! For some reason, I find that my best decoys are the cheapest SportPlast water keel junk I have iin my decoy bag. If you set the spread up correctly and have enough movement, the birds will come in. They're really not that bright! Dispite what the decoy manufacturers will have you believe.
One last thing. When I was a young college student who couldn't afford the paint for my decoys, we used old wooden hand carved decoys that we flamed to look like black ducks, We used whatever stain we could make to fill in any colors, and basically did everything ourselves. If you looked at the blocks, you'd have sworn that the ducks we killed needed a white cane or a guide dog to bring them into the spread. But we killed a lot of ducks with them.
