I don't know about you... But I'm not shooting my bow at atlanticc city for thousands of dollars lol...
I'm shooting at a deer at 15-20 yards 99.9% of the time...
My Muzzy's have never let me down if I do my part...
As far a spin test... If I have one that spins a little funny... I've fixed the prob by heating up my insert and just turning is a little...
I guess you cant do that if you shoot carbons huh???
