Yup, probably what Paul said or maybe a little burr on the jaws of your release. I hope you've changed that loop a few times in those 3 years.[&:] One of my friends had such a bad habit of pulling up on the loop from the get go that he ended up actually sliding the loop up the string enough to cause the serviing to separate on his string. He couldn't figure out what was happening until, I believe it wasLen watched him shoot and told him he was drawing improperly.
