Depends on what you want, lightweight or realistic. I have a "Purrfect Pair" of Montana Decoys and they're great, but for the realistic setup I used to use Avian X. Then when I almost passed out trying to blow up a hen decoy as I could hear a gobbler getting closer I sold all of my Avian X and started collecting DSD. More space needed but I save brain cells and don't have to worry about bad shots poking holes in my dekes.
