I'd definitely lose the high poundage bow. No need for it, and its just no fun to not be able to take more than a few shots per practice session. Not to mention sitting motionless in a cold stand for hours, just try to pull it back.... it won't be easy. I'd get measured to find your correct draw length then figure how much you want to spend on a bow, be it used or new, then shoot all the bows you can in your range and pick the one that feels most comfortable for you. I'd probably get a release, it does help with accuracy. Good luck!
