I wouldalso look at draw length. is it at your setting or adjustable enough. 70 - 80 pds. is alot of weight to draw. especially on an older bow w/ virtually no let off !! LOL !!! Might be a good way to put a down payment on something newer. Or sell out right for cash for upgrades on another bow. Definately wouldnt recommened shooting this tank w/ problematic shoulder issue's. Good luck !!!
