Ray,
One of the problems I have experienced with another brand of small game head that had a wider diameter and extended "claws" (or "ears"), like the SGT, was having the screw-in shaft break off from the lateral force of the head hitting hard objects off-center with a claw on one side of the head. Have you had any reports of customers experiencing similar breaking of the SGT shafts? I would think that would be a potentially common problem. When I use a head that does not extend beyond the diameter of the arrow shaft, like a blunt or a hex head, I have never had that kind of breakage, for fairly obvious reasons. I did receive one of your SGT heads with my order, so I am going to give it a strenuous workout to see if it breaks on me. If it doesn't, I will buy more of them.
