Terry--you're on the ball--the 'Windstalker' is quite a neat cable guard--does remove some cam lean and produce about 5-7fps ( I can speak for my bow).
What I like the most is that the arrow seems to group even tighter--could be all in the mind--but I do like The Windstalker--I'll be willing to answer any questions you may have.
As for the STS--I had it on my Allegiance (rear mounted)and removed it, as I could NOT stand the way it kept getting in the road everytime I tried fitting my hand in the sling.
The arrow did leave the bow 'faster' with the STS fitted and flew well--but it's making contact withmy 'inside wrist' and I cannot handle (mentally) the feeling.
John--here's the link.
