Sorry, to ask this, but are you sure it's the rest that's making the loud noise? I have the Ultra-rest Pro and I can't hear it at all. I know it does make a sound because it hits the shelf, but what I do hear is the thump from the bow string, then the arrow hitting the target. BTW, I'm shooting a Mission Eliminator. You may have done this already, but you could confirm the sound by engaging the rest to full position with the lever (without an arrow and not drawing the string), then releasing the rest. This may help rule out if it's the rest, s specific part of the rest release, or suggest something else/additional is generating the loud noise.
