I agree with Fireduck 100%. I have Final Approach, GHGs and Bigfoots and I can't tell the difference between any of them out at 100 yards. Fireduck also hit the nail on the head in reference to location. If you're in the right spot, you'll get geese. I have the new GHGs and am not satisfied with them. Sure, they look awesome and have all kinds of crazy head styles, but they just don't hold up like a Bigfoot. I'm buying all Bigfoot next year. Also, I'm not so sure an experiment involving two separate decoys spreads in the same field with two different decoy brands will be accurate. Different locations in a field can make a world of difference in whether the geese will come into a spread or not. Also, each spread would have to be set up identical and I don't believe that is possible unless you get out there with a tape measure and plot out every single exact location of every decoy in both spreads and have every decoy facing the exact same way in each spread, etc. Bottom line, if you have a good decoys (GHG, Bigfoot, etc.), a good set up with not necessarily a lot of decoys, in a good location, you'll get birds.
