RE: Shooting unfletched arrows
I' m assuming (dangerous exercise, but it' s all I have to go on) the pro set your timing or cam synchronization correctly, set you up with the correct spine arrows and set the nock point at 90 degrees. Do not lower it below 90 degrees. If you have to go below 90 to get a bare shaft to fly straight, then you need to adjust the bow' s tiller.
