I shoot my bows better with a bow quiver on the bow........with that being said. All bow quivers will effect the bow in some way or another, no matter what weight, style, etc. I have never based tuning a hunting rig with just the results of a naked bow. Its not the tuning standard to base decisions from in my mind. I like to tune my bow as though it was sitting in my stand with me ready to shoot a deer. That means I tune it with a bow quiver attached to my bow. And it rides there all season. In fact it stays on my bow most all the time.
