We've never used the carry-lite flying decoys, but we've used goose magnets with great success. TO answer your other question, geese really don't care too much about mixed decoys. We hunt over 5 or six different brands. Also not all geese look the same. The subspecies all look a little different from size to color. As long as they are in good shape, I'd keep using them. Thats my opinion on it. Good luck!
