Not like any of the suggestions need reinforcment... but I agree on re-thinking the strap on. I also have several of all the brands mentioned. My favorites are the ones with straps as opposed to Velcro (I like those too, for some types of hunting). I deer hunt with the strap types because I like to remove my quiver when I stand hunt and hang it up beside me. My thought is that waving those bright colored fletchings around when I'm trying to be unnoticed in a tree stand seems counterproductive.
Most of my Velcro style I leave on the bow (except for take down and transport) and they are generally ultra light 2,3 and 4 arrow versions on narrow longbows I either use for stalk hunts or small game. All of the 6 or more arrow quivers on my recurves are snap-strap ones. They aren't the top and bottom connected models but I have never had any trouble keeping them together until the foam gets wore out and then they don't hold arrows well anymore anyway so it gets replaced.
The insert styles look fantastic... but the one bow I have that type of quiver on has always had a very slight buzz that I can't get to go away until I remove the quiver. The insert doesn't seem to be loose. Not sure what's up with that one.
Really... It comes down to what works for you and what looks good for you (first kind of cool, second kind of cool, as I have heard it described). I look at quivers the same way I do socks. I may have only one pair of hunting boots but lots of different socks for lots of different situations. None of my quivers have holes in them though (and they don't smell weird either).
