Great points, and I've had to deal with that problem in the past too. I was hoping to find something that packs small and light enough to just put in my current pack. That way, if I find a good spot that doesn't have any trees to either climb or use my saddle on the ground, I'd have an option that doesn't include sitting uncomfortably on a log, rock, or the ground.
I guess I could use the Waldrop to carry everything and leave it at the bottom of the tree if I do climb.
Would you say that it's possible to open and set up your ultra light chair with minimal noise if you really tried?
