Which NAP rest do you have? I am using the Apache which works great. There are plenty of other good choices though. The trophy ridge revolution, the ripcord, trophy takers, and various other drop-away rests. The one problem I hear about from time to time is with "bounce-back" on some drop-away rests. If it drops and bounces, it can contact the FOB a little on the way through which will affect flight. This can usually be resolved by adjusting the timing of the drop-away.
