I also have an MA11, 64". I got this bow with the BW 5/7 quiver. At first I shot the bow without the quiver, because I have never been a big fan of bow quivers. One day I decided to put the quiver on and try shooting it. I loaded it with just 5 arrows and was really surprised at the feel of the bow when shooting. The BW quiver angles the fletching back a little and the bow did not feel lopsided with the extra weight. Now I shoot that bow with the quiver on all the time. My arrows are about 30", no problems with fletching clearance from shaft to shaft.
