I was the skeptic that wrote the post talking about the STS. The STS is worth trying for yourself to see if it makes a difference. I didn't think my Allegiance vibrated that much or was that noisy until I put on an STS and shot.

WOW!!!

When I removed it the difference was noticable. My rig now is quiter thanothers at a much lower draw weightI've heard at the range. I removed my string silencers and added the serving.

Mine is just off the string. You have to play with it to get what's right for you.
