Thank you guys so much. It sounds like the Openshot may be my best bet. I dont have a big beer belly so I should be OK,

(maybe just a little). Anyway my current climber isn't a sit and stand style, it like the openshot but the top piece has the bar all the way around it. I should be in shape enough to climb with it. Im just afraid at 6'4" it may be a little to small for me.
Just so ya'll know- when I say pack it in, I mean I will be walking a while, not 1/2mile. Probably will be carried in well over a mile on many occasions in the warm Arkansas archery season.
I will also look into the other stands, however Im not really considering anything close to 20 lbs. cause my current one is a really good stand just a little heavy on those long walks. I was in mine today and was actually thinking about cutting the front out of the top section making it open in the front, my legs are almost too long for it. It kinda gets in the way of my knees sometimes.
Anyway, thanks again for the help.
