Thanks buckeye! I'll definitely keep an eye on it... And thanks for the post; that's exactly the kind of stuff that makes HNI invaluable -- no bashing, just straight-forward facts from one archer meant to help another archer.
I know Matt / Pa has used this particular rest for a while now with no problems; it's actually on his recommendation that I'm ordering one.
I have an APA Twister Safari SL on my Patriot and really like it. But I will definitely watch that pin. Have to say I am surprised that it would snap though.
