Well, unlike all of the experts here, my technique has changed dramatically over the past year as a result of re-designing my skiing from the snow up. Back in the straight-ski days, I was a decent skier. Earned a gold medal in NASTAR, placed first-or-second on my high school ski team back in the late 70s, and generally skied as well as any of my recreational skiing friends.
However, I didn't know enough to try to change my technique based on the capabilities of the new skis. All I knew was that it was suddenly much easier to turn. I still used an A-frame, and even tucked my downhill knee.
Last year, however, starting with a few recommendations by Rusty Guy early in the season, extending to clinics with him and with PSIA-RM examiners, I changed my skiing. I discontinued my outside-foot-prominent stance, developing an ability to more evenly distribute weight between both feet. I incline much more than I used to (I think--I haven't seen myself in video or photo) in order to balance over tightly carving skis instead of using a ton of angulation. I also keep my skis on the ground through the entire turn, rather than using any unweighting at all. And I used to use many different kinds of unweighting: up-unweighting, down-unweighting, White Pass turns, skating, on and on...
The fundamentals are the same, of course. There are only so many things that one can do to skis (as Rusty mantras: rotate them, press or lift them, and tip them). The blend of these changes based on the particular ski. Today, I think, more than ever before, one has a much easier time accomplishing one's goals on skis. I know that I do. At 43 I am able to ski more dramatic lines with less energy than ever before. That's a good thing
as far as I'm concerned!
