I just bought the Martin STS for my 2009 Cheetah and it doesn't seem to fit. My bow has the hole in the back of the riser with the set screw on the side. I was under the impression the STS just slides in and then you tighten the set screw. The one I bought is a Martin STS which said it was for most '09 bows including the cheetah. The STS will only just barely fit into the riser and then you are unable to adjust it in either direction. Just wondering if anyone else has had this issue. Guess I'm just going to go buy the Limbsaver STS with the front mount. Let me know if I'm missing something.
