Yea, you don't shoot groups with those, after I hadBeemanarrow explode on me this summer, I will never shoot groups again. I hadn't even shot groups before it had exploded so I have no idea how it got damaged but I definately wouldn't shoot for groups with these expensive A/C/C's I shoot.
The charts told me that I can shoot these in my new Vectrix as long as the poundage is no higher than 65# and since have a dozen and a half of these and have become real fond of them I told my dealer to set my bow on 65#. These A/C/C's spoil you. BTW; you are under priced on your arrow price; they are $140 a dozen, $11.66 each
