My wife and son did the shooting exam this past weekend. Both shot well and I was proud. I did learn something about heads and what I thought was legal. Shuttle T's are considered barbed due to being 90 degree from the shaft, and Rage heads are legal mech heads as they due fold back to less than 90 degree if you push them backwards. I know from the history of this sight these are issues we (as hunters) go back and forth on. Just FYI for anyone who had questions on this.
