My dad and I have had great success with our Pretty Boy. In about 3 years of using it, we have only had 1 tom shy away from it. He was actually in range and I had a shot at one point, but I was wanting my dad to get one since I had already tagged one. He never had a clear shot and the bird skirted around at about 35 yards.
Funny part is, we caught up to him in the field a few minutes later. I clucked and purred and he came across the opening of the logging road and my dad missed him.
