I think it comes down to where and how you hunt. If you have a private spot somewhere and you dont hunt it too often, then those decoys would probably work. The flip side is when you hunt public, and maybe you aren't in the perfect spot. That's when your decoys need to be the best that you can get. Your not only trying to fool the birds in that situation, but your competing with everyone else. Your concealment, decoys and placement, and calling need to be spot on. I can go to this little private spot that Special T has been to, use the oldest blocks in my rig, and kill ducks all day. But anywhere public I bring the best I have.
