I've got a CQ-1, which has just the small storage on top of the quiver. I attach it to the outside of a cabelas backpack, which I already had when I purchased the CQ. This has served me well for the last 4 years elk hunting. It's very quiet, you just have to make sure the CQ is cinched very tight to the backpack so it doesn't flop around. I also run an elecrical tie through the top nylon loop of the backpack and the top loop of the CQ.
In answer to another question, I can't sit on the ground w/o taking the backpack off, but I can live with that. Also, with a little practice, the arrows are easily accessable w/o taking the backpack off.
