Camo cop,

To answer your question about the cinch strap. When you use it the bottom and top are locked together rock solid. On your summit if you lift up your foot platform it could slide down the tree or if you have ever worn bulky clothes and you are wedged into your sling seat, when you stand up your top platform comes with you. I had a summit and everything else and they have all done it. I think most recommend attaching a rope between top and bottom platforms in case bottom falls. Don't have this problem with the equalizer. My 2 cents worth.
