I assume your attaching a strap to the versa button and then pressing down like a climbing stick. Your platform mounted at the bottom is acting like a lever which is going to pull the top standoff away from the tree no matter how much you preload it. My platform is between the standoffs and my strap is attached to the platform itself. While folded up I take up the slack and open. Stap is level around the tree and the platform and when I open the platform, it compresses the whole thing to the tree. If done properly, the whole thing will stay firm to the tree. No pull away under load. Hope that makes sense.
