Does anyone have any specific experience with the mount to your bow arrow holders like those offered by NAP and GKF? NAP has one that mounts in your berger button hole, " arm" holds your arrow on the rest prongs until you draw, and then it flips back out of the way.

Do they work as advertised? Are they silent during operation?

Any input is appreciated.

I' ve narrowed my rest choices down to a Bodoodle Zapper 300 or a GKF power drop with an arrow holder. At least for today
