After using the Montana Bow Sling for a couple days antelope hunting I think it might be a game changer for me, just like the Kifaru Gunbearer. I am liking it WAY better than the Primos style slings or attaching the bow to my pack while hunting. I customized the straps and buckles and added a second triglide to get my bow to ride perfectly on my Reckoning. I set it up for the bow to ride under my left arm with the string down, top cam forward. It does bounce/swing slightly, but a little pressure on the bow from my arm keeps it pretty negligible. The bow goes on and off the hooks very easily, and the straps are out of the way when the bow isn't on them, and the straps can be easily removed if you want to take them off or switch packs (at least the way I have them set up with an open-ended Kifaru female buckle attached to the pack's webbing). One huge benefit is having both hands free to use binos without having to set your bow down. Although, if I was going to use trekking poles I would still almost certainly lash the bow to the back of my pack with a Grab-It. But since the system is so light, I would still definitely bring the straps on backcountry hunts. Construction appears solid and components seem to be of high quality. The buckles are also compatible with Kifaru buckles.
If you hike a lot while hunting this is definitely worth considering, especially considering the relatively low price.
