Alpine soft loc. Quiet comming off, quiet going on, mount damps vibration, easy to attach an extra quiver mount to a tree and clip it on the tree while in the stand.
I have not had a single problem with mine (only 2 years.) and the various mounting options REALLY came in handy with my drop away arrow rest (A little big...normal quiver location woiuld have been in the way).
The ONLY thing agains't it, is that the mount is a little wide,,,make sure you have a wide enough bow case (if you use a hard bow case).
