you might try marking your arrows and see if you have one or two that are not flying right. I had one that gave me fits for a few weeks, until I noticed it was the same arrow hitting the same spot left and high every time. I almost developed target panic because of that arrow, and it had me shooting really inconsistent, then I told myself to let a bad shot a go and concentrate on the next shot. I started hitting the bulleye with all except one arrow and it was in the same place each time hmmmmmm, marked that arrow and no matter what it would fly weird.-Steve
