I can hunt out of my saddle for hours without getting uncomfortable by changing the length of the strap holding me to the tree.
I guess that the Tree Saddle is one of those things that is not for everyone, and some people will shy away from it because it is unusual and not traditional.
Thanks for the info guys, I will probably buy either the Guido or Tree saddle Ambush. The ambush appeals to me more simply for that it only weighs 1.5 lbs.
