Has anyone else tried one of Dann-o's Heavy Duty 1 " Sliders for attaching your tether to bridge. I have tried it from the ground, seems to work great gives you some crazy good adjustments with no Carabiner or Prusik. Just some info: when he states heave duty 1" slider it is just that, very heavy duty. If you try it be sure when you disconnect from bridge you make a loop around the slider, it could slide off. Good or bad idea?
