Do you know how to rappel on a regular rope diameter? If not then no chance in hell. If you are already an expert in descending a rope probably not. The most experienced climbers in the world use 5MM diameter minimum and that is scetchy.
Where are they teaching this?
If rappeling is at all new to you then forget this nonsense. I have been climbing for more than ten years and I would not want to try it.
Got some links to others using this system?
