I have owned an API Grandstand Magnum for quite some time. But, over those years I've also tried at least 4 other brands of climber. Each one I tried was hunted out of at least three times, and I tried them all on virtually every type of tree on my property, so I think I gave them all a good chance. Including my API they all had one little "flaw" as far as I'm concerned. Once up the tree and the seat part firmly locked(strapped) in, the foot part was not as stable as I would like. Each one had some "roll" to it if even a small amount of side pressure was put on it. The only one time Ii ever felt totally secure with the foot part, was when I belted in real well and lowered myself to a sitting position on the foot part, and actually put a ratchet strap around the tree like the seat part uses. Guess my question is two fold: is there a climber with a rock solid foot part, and if not why hasn't anyone ever made one that can somehow be tightened from the seat part?
