I know most of the 4 or 5 people who read this blog are so damned good at skiing they think improvement, or trying to improve, is for lesser humans. Each of you would enjoy laughing at instructor-speak or coach-chatter. "Hah, I just click in and go, never think about anything, I've been Best Skier at my home ski area since I was 2, why would I have any reason to think about ski technique?"
I understand. It's a burden being at the top of Maslow's hierarchy in everything you do, and having to spend an entire life there since you hit that apex around age 2 or 3. Most people work their whole lives at something to get somewhere in the middle of Abe's pyramid.
But for the occasional person who arrives here by accident or because someone somewhere told you, "go read that insane reactionary asshole, see who he's trying to boss around with his caveman views today," maybe you're curious about skiing technique because you're not one of those Born Masters.
If that's the case, you could do far, far worse than to read posts by username Metaphor_ at EpicSki.
This post is a perfect example of his pithy, neutral and wise observations on one of the commonest mistakes people make when talking or thinking about "expert skiing" -- which I put in quotes because it'd be a level of pseudo-expertise the person's inhabiting if he or she is following the thinking that Metaphor_ kindly and wisely corrects in the post.
Ultra-focus on "shin to win" or "stay on the balls of your feet" usually comes from someone who hasn't experienced great skiing through either vehicle. Usually it's being said by someone who is repeating what he/she heard somewhere else and, maybe, what he/she has been trying to do when self-teaching skiing.
The emphasis on power point @ rear of arch = priceless, bullseye, etc. If you're on the balls of your feet, you're the same as the MTB rider who is descending in that endo-prone, imbalanced position with body momentum capable of tipping over or rotating around a point somewhere ahead of the front axle.
