RE: Treelimb quiver and HHA Optimizer sight
Which HHA are you talking about? They make several different 5000 series sights.
All of the HHA sights come with a quiver mounting bracket that allows you to mont the quiver over the adjustment arm.
I have the DSXL5519 and had to use the Kwikee riser bracket behind the sight and mount the quiver on it above the sight. It worked out really well. It gets the ends of the arrows above the cam and moves the quiver back a couple of inches.
