I used my brothers Lone Wolf climber on a couple hunts last year. He has the hand climber model. In my opinion it's the best stand I've ever used. Not only was it light weight but it packed down nice and flat. My only complaint is that the seat wasn't the most comfortable for a long hunt. I see the sit and climb model has a different seat which looks more comfortable.
Another stand that has caught my attention is the new Summit Razor X5. That stand is also light and has the adjustable shooting rail. And it's $100 cheaper than the Lone Wolf sit and climb.
I don't know if the sale is still going on but
www.keystonecountrystore.com was selling the Lone Wolf sit and climb last week for $305.99 + s/h.
