I've been using my quiver caddy for more than two decades...and hands down it works best for me. Even in the thickest brush. I used an Asbell style quiver option of my own make in developing the quiver caddy, and liked it, except for one thing....another strap around my neck to add to the tangle already there.
People who say they prefer a bow quiver in the thick stuff over a hip quiver, really have never tried these good options. The "old style" hip quivers that strap to your leg and hold your fletches up at an angle in a more rigid way can certainly cause you trouble, but the quiver caddy and the asbell style allow you the flexibility you need....and without the long "lever" attached to your arrows that your bow becomes in navigating thickets. Think about that!
There is no easier on/off quiver option than a quiver caddy, and it works everywhere for me, better than the rest.
