Thanks for the feedback WBT - "he had passed through the steepest area of this run and was in a safe area. He just let it rip like a lot of us do from time to time when there is run out."
Like you say: start small, get experience and control and then go for a planned big one. I understand how a man was killed on those rocks to the left, especially at the end of a day if you are too tired to walk down and think this is a faster way.
