Worlds Hardest Ski Run? - Swiss Wall / Chavanette

With 2m high moguls The Swiss wall is often referred to as the hardest inbound Ski slope in Europe and potentially in the world. If you think you know of a harder marked trail then let me know so I can go visit!
This run starts on the Avoriaz side enabling the bravest skiers to cross the border from France to Switzerland.
