Limb-mounted quivers always affect the arrow tuning, at least for me. I shoot a Mentor as well, have owned several of them, and on every one of them my strap-on quivers will cause perfectly tuned arrows to show stiff if they are tuned without the quiver. I like the EFA strap-on limb mount quivers; they seem to work like Limbsavers in quieting the bow and dampening vibrations, but they definitely affect arrow spine. I used to use the slide-on Selways, but they are heavy as a stone boat and can't be taken off easily. They unbalance the bow too much for me. If you have the riser inserts for a bolt on, that is surely the best way to go, and lots of companies offer that option, including EFA, I think, and Great Northern, both of which are lighter than Selways, in my experience. Great Northern's version has, I think, knobs which allow you take the quiver off and on quickly. Mentors are fairly heavy as recurves go, and some people don't like the extra weight on them, but I do, unless it is a 64" model, but Selways added too much weight on one side for me. YMMV. Paul.
