Great video. Anyone who is learning to ski switch from scratch should focus on being just as good at looking over each shoulder. Many people (myself included) master one way and then learn to do the other later on. It's easier to learn both at the same time and you will probably be better off in the long run. I can do just about anything over my right shoulder but am not nearly as comfortable over my left... Once I get going really fast over my left shoulder it feels sketchy - I can go as fast as I want over my right with confidence and it's frustrating to not be able to do both. Nothing to me is more fun in skiing than just blasting down trails switch with good form.
