I don't have a strong feeling one way or another. I personally have had them help me and also hurt me on certain hunts with birds either running into a set of decoys or shying away and circling around them. Sometimes I use them but often I don't, depending on how I choose to hunt that area/day and what I think the conditions call for. In any case, as usual I feel to each their own, hunt however you like and afford me the same opportunity. They certainly are not a cure all or unfair advantage, IMO.
