Pretty sure the guy making the "Climax" has retired, and I don't think anyone is making them anymore.
Some links to several good stands here, but one thing to think about when hunting these irregular trees.. (I know I love the concealment too,, but)
If you are wearing a fall restraint (Whomever's) and you fall,, How to you get back to the tree?
If you can't get back to the tree and relieve the pressure of the harness, you have precious minutes before you black out, and if not recovered soon, probably for good.
