RE: aftermarket STS type systems
These systems work well. They do make a difference in the "after the shot" feel of the bow.
However I wonder about the abrubt "stop" of the string as it makes contact with the STS.
Now, let me say, I have an STS onmy Switchback XT so I'm not bashing it. But I'm still a bit leary of it after seeing some hig speed cam footage of a bow being shot with ans STS on it.
