I use the rock climbing harness. I haven't had a fall from the tree YET but I have used it in place of a stand and you can sit, hanging from it for a good, long while, comfortably. I keep the slack in the rope short, so I'd only fall about 18" MAX. Usually my safety rope is just tightening when I sit down. I hook in the front and figure, at worse I would be whipped around to face the tree. The rope can get in the way and sometimes forces me to do a 360 turn to be able to make a shot but it seems like a good system and helps hang my stands if I use it like a lineman. BTW, you can by a chest harness addition from the same manufacturers (ie. Black Diamond etc).
