RE: is a sts really worth its weight?
I like the super leaches. They last a long time and really do a number on string vibe. I have a set I'm debating on throwing on my Allegiance. Actually, the debate is over, I blew my stock silencers off already. About 150 shots is all it took on those stock jobs.
Though somewhat controversial, another thing the STS systems help with his string slap. While I agree if its a problem, you should check your draw length, for hunting, the STS helps. We sometimes have to wear heavy clothing in cold temps. The added bulk on your bow arm can get in the way. The STS stops the string before it can get into your arm.
Some report added accuracy, but I am skeptical about that. Though stopping the string in the same place each shot does make sense.
