I'm also from MN. I have an old Trophyline treesaddle and helium sticks. I've replaced quite a few things on the saddle itself like the shoulder straps with a cheap treestand harness, the tether with a climbing rope, carabiner, and prusik knot, and the lineman's belt with a lone wolf strap for their sticks. I like to dink around with that stuff and it makes it lighter. I climb with 3 or 4 hawk helium sticks. The bottom one has a two step aider from EWO outdoors.
I really like it and I agree it feels way more safe than a small hang on stand. It sucks in super cold weather, but I'm usually good through November.
Shooting is definitely different, but I feel like it opens more angles than a hang on. I practice by hanging off a post on my deck.
