One advantage that many hard snow skiers may have is that if they’ve learned how to engage a ski, bend it, and have the tail follow the trajectory of the tip, it’s not that much of a change to ski deep, untracked powder. If, on the other hand, your default move is to push the skis to an edge, you are likely to become quickly tired, not have much fun, and make a short day of it. Powder skiing is another place where finesse beats power, most of the time.
So, learn to stand in the center of your skis and let the skis do the work for you.
