I share your aversion to putting bow quivers (or for that matter, carbon arrows) on my Hills. I also don't wear sneakers with dress suits or put pickle juice on my icecream. Call me crazy.
Back quivers seem to work best when:
1.) They are supple enough to conform to the flat of your back/upper shoulder (more comfort, less bounce or roll, better for keeping arrows from rattling around).
2.) The quiver is worn at a slight angle such that the opening is roughly behind your 'shooting ear'. Lots of folks seem to like a more severe carry angle that puts the quiver almost diagonal on their back and the opening further from the top of the shoulder. To each his own, but that position makes it harder to access an arrow and requires either pulling the strap to raise the quiver or using the bow hand to 'bump' the quiver base and push the opening up and towards the ear for grabbing the nock end of the arrow (the right place to grab one). The latter can be a bother and more than a little annoying in tight quarters.
3.) Use a quiver that is smaller than larger. Large quivers are both heavier and harder to maneuver than lighter, less bulky models. Be careful of adding to much 'stuff' into/onto quivers (knives, hawks, antler decorations, strapping on spare clothing, etc.), since this can affect how it balances and rides. If you do add stuff and it has much weight, best to keep it lower than higher so that the quiver's center of gravity stays low. Few situations require carrying more than 6 to 8 arrows and since smaller quivers are easier to maneuver in the woods/brush and weigh considerably less if made of leather, they make sense in most cases. Synthetic material, though not as "cool" or traditional as leather, is often much lighter and in that sense does have it's advantages.
Other than this the best way to find what works for you is via trial/error/regular use. Back quivers do grow on you if given the chance. I hardly even notice I have mine on anymore... sorta like an old favorite hat.
