Another vote for the Summit. I have a couple of the Gorilla harnesses that came with my stands & have tried to use them in the past. You're absolutely right about them being very restrictive. The teather on the back can't be more than a foot long. Feels like you've been tied to the tree. Check out the Summit. I think you'll be pleased.

But don't get rid of that Gorilla harness. I really like the way the climbing system works. That's what I wear when I'm hanging my stands in the pre-season. Gorilla for hanging, Summit for hunting.
