I agree there is no perfect quiver for ALL needs. The Selways work well enough, but can be a bit bulky from a traditional standpoint. I use 'em though.
I never did get the hang of back quivers for serious hunting. They sure look good and carry well however.
Side quivers can be effective... if you learn how to move through brush with them. They require too much attention for my taste.
If you don't mind drilling a couple of holes in your riser and placing a couple of bushings, the Kwikee Kwiver is hard to beat. You can carry it on the bow and take it off at will, plus you can buy quivers whcih hold as few as three or as many as 6-8 arrows. The Kwikee is about as close to an "all-around" a quiver as you can get.
The Great Northern is second to none, wraps snugly to your riser and is trim looking on most bows. I don't own a GN, but wish I did!
If I HAD to have one quiver only, it would probably be the Kwikee, but the one I use the most is my Selway 4 arrow bow quiver with a rawhide cover (for asthetics of course

) even though I prefer to shoot a bow without a quiver. Ground hunting is my usual tactic and there is something to be said for having your "weapon" and "ammunition" in one package.
