RE: NAP fall away rests
I installed my 4000 after the close of the regular deer season. I believe it's all in the tuning mine is super quiet. If there were any negative comment it would be that my broadheads now shoot EXACTLY where my target arrows do. Lost two arrows to broadheads messing them up and I have seven arrows that need to be refletched. I cannot shoot any arrows at the same spot on my target.
It is a wonderful rest and more than worth the time to do it right.
By the way after installing it [following instructions] the first two target arrows were dead bulls and the third arrow, a broadhead sliced through the vanes on the two target arrows. And that AIN'T too bad!
