Thanks for the info guys.
Jim I am 6' and 225 lb, so my butt I bet is a big as yours. I doubt I will make out any better than you. I bought the Walmart one to try, so if it doesn't work out I can return it easily. If it doesn't work out, I am going to try the REI one. I need something light and compact, since I go out before light and stay out until after dark. We usually hunt far back in to get away from presure. This year I want to strictly still hunt, so I am going to be moving most of the day. I am tired of going to neet places to hunt and staring the same 30 trees for two weeks in a tree stand.
Thanks again everybody.
Gil
