It really comes down to personal preference.
I really like bow quivers, to me the extra weight helps stabilize the bow and I actually shoot better.
But with that being said, when I took my selfbow to Alaska, I used a side quiver, but it ended up being strapped to my Schuh pack. It also gets in the way when wearing my Pack Idaho pack, (now Bison Gear).
The same goes with back quivers, just do not work well while wearing any type of hunting pack.
But I can see the benefits of having a detached quiver maybe? while stand hunting. Either tree or ground blind.
