That was what I was wondering about Rock. Hooking them, means you can't slide a 3/4 up or down very much to adjust. But I got to thinking to just buy maybe 8 of them, put them in at differenent positions, one where the UQ is right at your shoulders, and maybe another set down lower or higher. So you can just unhook, slide down to the other set and rehook.
