Saw these used on some of Randy Anderson's dvd's. Looking for that type seat to use for coyote and turkey hunting. Any comments, good or bad? Does it provide enough back support to sit for extended periods of time? I normally lean against a tree, but sometimes finding the "perfect" spot isn't that easy. That weight of 2.5 lbs bothers me a bit, but with all the other stuff I carry, it's probably a mute point. I have used a similiar fold up seat for turkeys, but I really prefer to sit down on the ground. Apparently my "search" skills are lacking, couldn't find anything there, I appreciate any help....
