I got a quiver on the the first two cross bows I had and did not like quiver on crossbow,not only does it add weight it screws up the balance and the way they sit on the x-bow they add bulk which makes necessary movement to aim much more visable to the deer.
I personally use two hip quivers one for field points and practice and one for 3 broad heads which is on the belt that I hang up while in the tree stand. Mine is 11yrs old and is a PSE King I do not consider it any thing special but it has given good service. Lee
