If you have the money to waste you can try an sts and see how it works. However I have heard every version of this design (it's not new) and string silencers are more quiet in my opinion, especially puff balls or beaver balls.

I'm not saying the STS does not work, just that I personally feel cheap string silencers work better for much less money. Also keep in mind the closer the silencers are to your limbs the less speed you will loose. Get them in just the right spot and you may pick up a few FPS. And really only need one near the bottom cam if it's a single cam. I tried this for a while and worked just fine. I put two back on though just because is looked dorky to me. Then again my whole bow looks dorky.
