I'll post more in a bit, when I have more time, but I got on of these seats and it's the best all around seat I've used to date. I strongly suggest this chair.
I know there are other really sweet high end chairs out there, but given weight, size, ease of transport, comfort, setup time and quietness, this chair best met my needs. Once you do it a couple times, you can have it setup in less than about a minute.
My biggest requirement was seat height, since I have bad knees. Most chairs are way too low for me. The big man chair can get me to about 19" to seat height. If you're over 6' tall with bad knees, that's a huge factor.
And the bonus, Todd informed me that I was the first person to kill a deer while sitting in one of his chairs.
