RE: Climbers.
I also agree with the others..Don' t go cheep on your stand. I am a repeat buyer of the Tree Lounge. I am 6' 5" , 225 lbs, and I have never had a problem in this stand. I can literally spend all day in it. You can shoot both sitting or standing.
You can find some great deals on Ebay since $ is always a concern.
Good luck!
