I'll guarantee that the fletcings are hitting that rest!

I have an idea you centershot and/or nock height is out of whack.....basically your bow isn't tuned. Follow Legacy's advice and go to Easton's site and download that Tuning Guide. It will guide you through tuning your bow and you'll learn the necessary procedures to acheive proper flight. I recommend paper tuning and then broadhead tuning as per Easton's guide. Good luck!
