I have a 2010 martin cheetah bow and i need to know how to properly install the sts on it. I cant seem to get the set screw to hold it properly over time, so what can i do to fix this and how did you install yours? I dont see why martin didnt just put threads in the riser like every other bow manufacturer out there. The set screw is a stupid idea in my opinion. Anyways, how do i get it to hold properly? Thanks.
