Now you've done it. I saw the thread going but never really looked into the STS. I have a feeling this is now going to cost me $40.00. I can find very little info about it though. The most I could find in print was on the Archery Experts website. All is says is
There are two models to chose from one that mounts in the rear stabilizer bushing and one that uses a mount and screws into the front stabilizer bushing. Weight is minimal and it takes out alot of string buzz. The string stops in the same place shot after shot and will help tighten the groups up.
