I have hunted over all 3 and some other versions that I have made along with friends. The Flutterwing used to be a pain to change bands in, but I have heard they made improvements, not sure. The whipsplash is a decent one. I just went with the Knotty Duck as it can be ran from the front or the back and it's way easy to change out the tubing on the bottom if it breaks. Only draw back is I have had a few lost heads. They use a G & H field shell decoy. The other two brands use more of a modified or full body style of decoy. All 3 will work so, if you get a good deal pick one up. I don't seem to use mine very often, but some swear by them.
