i have a summit copperhead and love it, a couple of my buddies went out and bought one too and they love it. Other than those i haven't really heard anything about them though.
I concur.
I bought the lone wolf last year....and was going to utilize it in lieu of a new climber (with the sticks). I could never figure out a way to climb safely without working up a helluva sweat. I sold it. It's also not the most corfortable sit I've used, by far. It's a solid stand.....but for an all-out lock on application...there's better (IMO).
I've used a gorilla for one season, now.....and a Summit Copperhead for the better part of 2 seasons.The Summit isWAY more comfortable than the LW OR the Gorilla....and the platform is larger. I haven't seen one I'd trade it for.
