I have the STS on my Moab. After 3 years, not a problem one with it. I kinda liked the idea from the standpoint of getting a cleaner arrow release from the string. We all know not all nocks are the exact same fit on the string, and I thought that having a positive stopping place (or resemblance thereof ) would tend to make the arrows fly more consistently. A tight nock might hold on a little longer than a looser nock, but I think the STS should make that time shorter, giving a cleaner release and thus a more consistent flight. I don't have another bow that is similar to my Moab to compare noise with, but it is one of the quietest bows I have ever shot. I figured that had to be in part to the STS.
