I had very good luck with the Delta decoy last fall. It is a very nice decoy, that seemed to work well. Made of 3D foam, so nothing inside rattles or makes noise. And when you have one of those long days that you never see anything, go ahead and run a arrow into it. I dont think there are any scent problems with it either. Just treat it like your other hunting items, keep it in a bag, spray it down with ghost, and use some cover scents around it.
Just my 2 cents!
