Roy, Tony and all,
Watching Spanky's 4th video where he is drawing arrows from his quiver and shooting, you can see his bow hand or elbow (I use my elbow) go around behind his side to "bump" the quiver up from the bottom of the quiver. This gets the arrows up to the where the hand can get them. No need to pull on the quiver strap to move the quiver. Of course, your quiver and strap need to be adjusted to where it fits and hangs on your back correctly for this to work. I don't have a video camera, so I can not provide any back side views for you.
