I've used them and had good results once. But that result was very memorable. The bird was hung up , wouldn't move and hardly gobbled. After I did this he gobbled allot and came in quickly.I used both at the same time doing long aggressive purrs but then added this. Using a wing or pulling on a long loose coat or jacket sleeve make wing flapping noises. I also used my feet and a stick to push leaves around like the birds are brawling. I also used a box call to make a few short goggles. I shot my biggest bird doing this 11 1/4 beard with 1 1/4 and 1 1/8 spurs. I had the pleasure in Maine of seeing two flocks of turkeys come running across a field and start fighting . What a rumble and they made on heck of a racket.
