I have two. The one on my Widow is actually a RH quiver on my LH bow (quick detach limb bolt model) - this keeps the quiver in line with my riser instead of jutting towards the string. It does make getting the arrows out that are inside towards the riser though. However, mine is a 5-arrow quiver. I consider the back 2 arrows spares anyway.
I like my norherns. I have Thunderhorn also and like it -- riser mount screws. I only shoot recurves and don't like the strap-on style quiver. Even though I have these quivers, I may not use them to hunt with (a couple of my favorite recurves don't have limb bolts or riser threads). I don't like the change in weight and balance of a bow quiver. I'll likely use a hip-quiver.
