RE: I need the experts.
Take it to a reputable Hoyt Factory-Authorized Pro Shop/technician for assistance, someone you trust. It could be something as simple as an arrow spine issue or even a rest movement issue, but it could also be something in cam centershot/incorrect shimming, etc. Best to have a tech look at it especially if you have a trip coming up soon. This way you can be sure everything is as it supposed to be when you head out. If you cannot find it in a month's time, iMHO it's time to take it to someone who can better assist you while being able to actually look at it in hand. Good shooting, Pinwheel 12
