I have no idea what all yall r talking about. Sounds like either a war over who knows the most or one of u is old school and hates to admit that archery is not as complicated as it used to be. I just shoot my bow 1000's of times and get it as accurate as I'm capable of getting it and go to the woods.. I hate to say it but mechanical broadheads have made that easy on guys like me... But that's all I've gotta say ill let my shootin speak for me cause in the end if u hit where your aiming that's the only thing that counts!
