I went to Air Assault school in the Army which is all about rappelling, then used that in a few other Army courses. I've rappelled from cliffs, buildings and helicopters using the traditional technique, Hollywood and Aussie methods. I rock climbed for several years before and after as lead and belay but haven't been in a harness for over ten years.

Even with all that background, there is no way I would trust myself today to tie in, tie off correctly. I need a 'safety' to inspect what I do before going over the side. It's made me think of getting re-certified in rope work at a climbing gym just for my piece of mind.

I totally agree with Teslinhiker. With ropes, the RIGHT training is more important than just having the gear.
