I have really never had any issues with the traditional v bracket ladders. I use ratchet straps for all of the connections and never was worried about climbing the ladder to secure the top strap. Where is the ladder going to go with the brace attached to the tree and the two straps in an X around the tree and secured to the ladder section?
The jaws just seem to add extra weight to carry into the woods.
People take them down? All joking aside. How is it different then putting it up just in reverse order? I make sure everything is tight before I start and use a safety harness when undoing the straps around the top of the stand. To be fair I don't use the huge 2 man stands that take a crane to put up. I only use stands that I can manage on my own.
