I need some help . I am shooting a 50# @ 25" bow and was shooting 50 to 55 birch shafts @ 26 inch. They seem to shoot fine but when I put a broadhead on they go to where ever.I also read that my fletching should be of the shelf but mine over lap the shelf maybe a good inch. The bow is silent and fast just bad with broadheads. I have a garage full of different spined arrows and will start low and work my way up. I have no wrist slap and no bow slap. I am having a hard time just getting it together.Thanks
