no, I knew you could rap with an ATC, just didnt know if you needed to do anything else up top to set it up or if a figure 8 was prefered (which aparantly its not). I also just didnt know how to actually rap until last night, didnt realize it was as easy as tying in both ends of the strand through the ATC slots just like a belay and lowering yourself down.

Saw some people practicing it last night at the gym, they would climb 3/4 of the wall on TR and then grab another set of ropes on a different anchor and rap down. I also noticed they were tying a smaller section of rope in some configuration above/below the ATC that acted like a sheath for their top hand to hold onto. Is this some sort of auto-braking system just in case they freak out/are knocked out/whatever and release their brake hand? anyone have a little guide on exactly what was going on there?
