If you decide to put one on the bow, I don't think it will affect your shooting as it didn't do anything to my accuracy. I take mine off and put it back on without thinking about it now.
That being said, I really like my Tuff Safari quiver for hunting. It's quiet, covers and protects my arrows, I can carry some small stuff in the little pouch, and the arrows are easily accessible both taking them out and putting them back into the quiver.
Go on the shooters forum and you can see them at the top of the page.
