There's a lot of debate about GHG's vs. Bigfoots. We use both (obviously have only had the GHG's for a season, since they're new). I'd say the Bigfoots are more durable, but the GHG's look so much better that they're worth the little bit of extra care that must be given. When we sit in our spread in the morning and look out at the dekes, the Bigfoots look good - but the GHG's cannot be differentiated from real geese that have landed.
You'll hear lots of opinions on this I'm sure, but here's a couple pics to help show you the difference.

Trailer pics - dark (flocked) heads are the GHGs (of course, you could also flock your Bigfoot heads and make them look better - but this is a comparison of "out of the box". I think 2 dozen of our GHG's also have flocked tails, but the rest are all standard. There's also some Higdon's that may be in there (bought at the same time as the Bigfoots and look nearly identical with the exception of the feet).




Here's a pic in the field (the front one is a Bigfoot)


We don't seem to have a problem mixing and matching, but tend to separate them in the spread (putting the GHG's closer to the tips of the "U" so the approaching geese see the best decoys first). Used to use lots of shells, but as we've compiled more full-bodies we have stopped using shells (takes a while though - they're not cheap).
