I have used the spinning wings pretty much sence they have been out. Useing them is a diffrence like night and day. I to have had other hunting groups around me when useing these decoys and have had the same exper. of the ducks tornadoing strait down into my spread as the other groups just watched. Here in Minnesota the state has put aside certain dates that we can use them. The first couple of weeks is strictly regular decoys then after that it is game on. Another good decoy setup to use is the Mallard machine this works very well in putting motion into your decoy spread. I have had other ducks land right on top of the decoys with this machine.
