Ok cannonball, here is my MA....
first the good, this is solid skiing. lots to like. Smooth, good balance, good CSIA stance (even though I would prefer to see your hips more forward), good inside foot tipping on the medium radius turns especially. Early edge engagement at the top of the medium radius turns. Pretty appropriate countering. You are clearly in top ranks of CSIA and have clearly worked hard to create polished looking ski turns. I mean you all the respect that is due as I offer the following criticisms.
Now the things to work on...take my comments for whatever its worth to you.
I hate to say it, but yes, you have to work on your extension move. The problem is in fact that that you using the old school pop extension. It looks like your timing is just off. You extend too fast and too soon. This starts a vicious cycle. what must go up, must come down and you are fully flexed into a crouch at the falline. You want to be extended at the fallline. Then it appears you ride out the entire bottom half of your turn in a crouch at which point that ONLY option you have to transition into the next turn is in fact a pop extension.
This is especially noticeable in your short radius turns, though it appears more subtly in the medium radius as well. You extend rapidly at transition, flex rapidly before the falline, then ride the last half the turn in a crouch.
In the short radius if you watch this video frame by frame, you can see an awful lot of turns where your tails swish across as you approach the fallline then you hit your crouch at the falline with snow spray and everything flexed. Hardly any carving in your short radius, sorry.
Medium radius you're getting away with some decent carving, but there is still some weakness in the carve I see around the fallline, all due to the same issue. You don't pop extend as badly in medium radius, but still too much and too much flexion before the falline. On ice and such this would be a glaring issue.
The reason your tails swish across is because when you pop extend you unweight dramatically. Then you are using rotary mechanisms on weightless skis, so they windshield wiper across. What goes up, must come down. When you get to the falline, you're down and edging hard to regain some carve out of the turn which you get at the very end. But from that crouched position the only way you can get into the next turn is to pop extend again.
This is old school skiing
- Forget for a minute about your extensions. People have been bugging you about it and you're not feeling it.
- Focus for a minute on what you need to be doing at the falline in the meat of the turn. You want to be fully extended at the falline, not at the transition as you are now. Just try to focus on making sure the extension hits the peak at the falline.
- After you obtain that extension at the falline, hold it a bit longer, delay the flexion.
- As you finish the turn, flex to absorb, etc. However, this is also going to be your release move. As you relax your legs and release from the old turn your skis will become weightless, which will enable you to float into the next turn crouched in the transition. Then after you have started the next turn, begin your extension so that you end up extended at the falline, but not before.
That is ultra simplistic view and there are a lot more refinements beyond that, but I think you need to really think about the timing of your extension/flexion, almost to the point of making it completely backwards from what you're used to. Big payoffs if you get it. Good luck.
