RE: Mathews switchback quiver
There are places to mount on a switchback. You probably didn't notice them due to the camo film.
I recommend taking your bow into the shop where you will be purchasing the quiver. Buy the quiver you like (ask the technician if the quiver will work first!) and then put the quiver on your bow while in the shop. Then check for clearance issues with a full quiver full of arrows.
IMPORTANT: Don't push the arrows into the foam. If you have clearance issues, the shop may have hardware to eliminate your problems. If not, as long as you don't break the new foam, they should take it back without a problem.
Best of Luck!
Odds are you won't have a problem and if you do enough research ahead of time, you will chose a quiver you won't regret.
