I just bought me a Hunter's Safety System vest last year. If I hadn't done so, I would definately try this muddy harness out. It looks nice. But regardless if you use HSS or Muddy or the one that came with your last tree stand, it's always a good idea to be secured to the tree. A guy I worked with fell out of the tree while hanging a set last year, and he missed the whole season with a back injury. And he's lucky, because it could have been a lot worse...
