I bought my first bow in September and have been working out the bugs in my shooting. I have finally gotten to a point where my grip seems pretty steady and my shots have gotten more consistent but something is rubbing my left thumb at the bottom knuckle. After a hand full of shots it starts to get real sore. I have started wearing a pair of thin gloves and it dosen't bother me, but I would like to fix the problem. Do any of you guys have any recommendations on what to do?? Have any of you had the same problem??
