Jeff, I'm inclined to agree with Greg, only because you don't need the best features (light, pack-able, stealthy, ease of set-up) and seem to require it's worst feature (long term comfort). It's fine for 4-6 hours at a shot. If I'm sitting longer thats when I take the much more comfy, sit and climb, model. But it's still not super comfy (I imagine) like these giant padded offerrings I see by others.

Quite Honestly I'm a stander. I usually swing the seat at 90 degrees to the platform and use it as a shelf for binocs, rangefinder etc, and stand against the tree itself. Ifeel I amless silloutted that way and much more alert and still. A simple head turn allows me to look around without my shoulders and body moving.
