big diffrence to me.. even with the lightest bowquiver my bows still tune diffrent with and without a quiver, its enough to make a diffrence in my opinion. some quivers like the old deltas, are really heavy loaded.. I really like the convience of a bow quiver but dislike the added weight overall as well as the weight hanging off the side of the bow, also without a bowquiver i have less mass moving when preparing for a hunting shot, so i use a cat quiver of one sort or the other. all little things i guess but, ive found a bare bow to work alot better for me, so i dont switch quivers on and off.
