Quiver caddy is a versatile option, and the one we prefer as well. They are being made by Tim at Farr West Leather (sponsor here) now, and he's doing a fine job. He also has come up with a new hunting quiver utilizing the quiver caddy bracket, called the Absorkee quiver, and it's a real beauty and super functional too.
Here's a pic of my son Kory packing out his buck, wearing quiver caddy w/kwikee.
And here's a pic of the new Absorkee quiver. This pic is the prototype. I believe there are pics in the sponsor classifieds of the new design, plain, and one with a knife option as well.
