RE: STS... a tuning nightmare???
I currently have one on my Equalizer. It was set up by Gerry Carter of Circle C archery down here in Georgia. I did gain 5 fps but that was due to removing the string silencers. As far aslapping sound, I have only shot the bow indoors and it is one of the quitest bows I haveshot (better then my Outback). It did remove "all" the hand shock from my equalizer and currently still shooting perfect bullet holes.This is the first one I have hadinstalled on one of my bows so the jury is still out.
