I second IL-Cornfed's comments. I put a set of the "Crossbow" leaches that Hoyt is using on my Allegiance. There are a ton of shots through them and they are holding up like a champ. The original silencers Bowtech put on blew off in about a 100 shots on the top.

I do have a notion to give the STS system a try. Seems like it would work even better.
