Just remember that they do need some tuning on your part to begin with. You may need to tie in a second noch point to give the FOB some room depending if you have a short ATA bow. Second make sure you are clearing your rest. Third sometimes they hit you on the cheek in an "odd" place, just look at it as a kisser button and I think you will love them. Once I got them I went from shooting a paper plate group @ 70 yards down to about a 5-6" group. Hope you like them and feel free to ask question if you have a problem. Paul is a great guy and always willling to get you set up right.
