I don't have too much knowledge of high-rise systems and the sort, but after watching that video, I would NEVER use that system. I didn't even see a full body harness, rope protectors, and several other things. The way the guy was bouncing around, trying to show the strength of the system, only showed his stupidity. If there's any high-rise guys out there, I'd be interested to see what you thought about the system...
