I used a lone wolf strap as my lineman belt for a while, but I went back to the original lineman belt on my saddle.
The webbing on the original is not that heavy and I like that it's a bit stiffer than LW belts. So I replaced the heavy caribiner with one lightweight aluminum caribiner on each side. This allows it to be entirely removable. I use it as a backrest once I'm tied in.
When I use my LW Assault stand, I still use a LW strap as my lineman belt for my Gorilla harness. It attaches to both sides of my harness with aluminum carabiners. Once I get up the tree and the stand is attached, I attach my tether, then I un-clip the linemans belt and it becomes the lower stand strap. All of my carabiners are silenced with cloth tape, so I just leave them hooked to the harness.
Like Red, I'm constantly changing things up if I find a better way, or think there could be a better way.
But I'm happy with my current system. I feel light years ahead of where I was 20+ years ago.
