Has anyone used the tree saddle? Is it really as comfortable as the advertisements make it out to be? I have a bad back and somedays I have a hard time in a hang-on for a full day hunt. Also, I hunt in 3 different states and many different properties namely in PA and am looking for a cheaper way to make stands. Several of my out of state stands are coming up missing. I was wondering about your overall ratings of the tree saddle. Thank you.
