#1 is a steel heavy POS...
#2 isa remake of the old Loggy Bayou... which was a decent stand
#3 is 19# and Gorilla's version of andOl' Man Treestand (Gorilla bought Ol' Man a few years back). This would prolly be my choice due to the light weight and economical price.
#4 is a Brutus.. which are very well built but tend to be a bit on the heavy side... if the weight doesn't bother you.. this is one rock solid stand.
