I always run a pair of wooly whispers, seems to work great.
A light weight quiver bolted on may offer some increase in overall weight, help tame some vibe, but IMHO it needs to be of a rigid attachment style and of substantial weight.
I find the GN stuff to be too light and flexible.
Better to make custom brackets of stiffness and bolt on a Delta. Quiet and helps remove some of the bow movement at the shot.
I did in experimentation find that a 400gr arrow from a 55# SA2 was a bit shocky and loud. 480 grain arrows made things completely different
I've broken my wrist several times and it used to be pretty tender, couldn't handle hardly any shock. A well tuned BW with a decent weight arrow offered zero problems.
