This video is clearly out of date
Though Martin Heckelman is obviously an articulate and knowledgeable instructor, this video was produced before the introduction of shaped skis. So it fails to address the changes in technique that shaped skis have brought to the sport. In particular, one notices the emphasis on unweighing to release the old edges and begin the new turn. In addition, when describing making parallel turns, Martin frequently has a wedge entry to his demonstration turns. This too is clearly an technique that predates shaped skis.

Very high Quality
I gained a great deal of insight from studying this video. The result was a massive increase in confidence and performance. Thank you very much to Martin Heckelman -the producer.
