The 2 simplest solutions are either to:
Live with taking 2 seconds to remove and reattach a quiver in exchange for a streamlined design
Tie a loop onto the stirrup to use as an "extender" so you can cock it without removing the quiver.
I put the Trophy Ridge Quiver on and it’s not bad in shoes. Don’t know if it will work with boots. It’s not hard to get the Kwikee off but the trophy Ridge is really easy. I might just mount the kwikee on my pack. A strap might work in a pinch.
Thanks
