You asked for this via IM, so here it is ...First off we need to acknowledge that the terrain is relatively steep
(at least in the third clip), the snow conditions are relatively cruddy and the visibility is flat. As much as we'd like to see offensive movements all the time, unless you are a Kool Aid carrying ski God we should expect to see some defensive movements pop up in these conditions. In general I see good rhythm and flow down the slope and an overall good absorption of terrain. I'm also seeing some edge engagement above the fall line with simultaneous edge change and some great angulation occurring above the fall line. Your balance is pretty solid as evidenced by the tall stance and generally quiet upper body. BTW - the air in the third clip is especially nice with the style of the skis rainbowing in mid air and the very aggressive landing powering through the next mogul in a strong balanced position.
My first observation at full speed was that your flow was a little jerky. You're turning out of the fall line too quickly and then getting a little park and ridey going across the fall line. When I investigated to find the root cause I came across a dilemma. Normally in crud/powder, you do want to close your stance up a bit and stay more upright over the skis. But you are able to get some nice powerful angles going in this snow. In this case, I'm expecting to see a little wider stance width and more long leg/short leg differentiation. For the turns I'm seeing here, I'd like to see even more aggressive edge tipping above the fall line to compliment the nice angulation that you are building. Using a wider stance width is the first component of getting the more aggressive edging to occur.
What I see in many of the turns is a heel push and some skidding as you pass through the fall line (e.g. tiny little bits at 7 and 8 seconds, 18-19 seconds, 23 seconds, 1 minute [using original time coding or 25 seconds for you viewers at home] ). In these turns your highest edge angles come at about 30 degrees after you pass through the fall line. The visual cues say that the highest edge angles should come at or near the fall line.
The next thing I see in many of the turns is an up move at turn initiation. I love the cross under move that you do after the up move, but I'd like to see more cross over in these turns too. To get there we're
going to need to get the hips moving inside the skis earlier in the turn. A wider stance width is going to help allow the inside leg to flex more at turn initiation. This will help get that hip moving. But we've still got a bit of a catch 22 because the heel push after the fall line puts you in the back seat briefly. You recover nicely by cramming the ankles forward, but now you've got no forward movement left to go "fore-agonally" into the new turn (what the visual cues calls forward and lateral contact with the boot cuff). So we've got the up move causing a delay in getting onto the new edges aggressively, causing the need to heel push to get out of the fall line, which causes the need to do the up move. Uh oh.
How are we going to break this cycle? Let's compare two different turns for a clue. In the second clip, right before you come up to the camera (1 minute 1 second in original time code) you are making a left turn. As you're entering the turn, you encounter a little mogul that deflects the inside tip. I see a great recovery and re-engagement as you enter the fall line, but freeze the position there. Check out the banking with respect to the inside hand and shoulder being lower than the outside hand and shoulder. Next comes the heel push of the outside ski, and the inside ski comes completely off the snow all the way to the toe piece. See how both legs are flexed almost equally throughout the whole turn? OK, some of this is probably avoiding the cameraman, but I'm only giving you a free pass on that for the last part of the turn finish. In the third clip, the turn after the landing of the jump is the reference turn I want to you have an image of. While you are in mid air, the extension of the legs to absorb the landing is accompanied by an extension of the ankle to push the tips down. As you land, notice how you bring the inside hand up vertically as you enter the fall line. Entering the fall line, the hands and shoulders are more level and the hips are further inside the turn than the turn in the second clip. The corresponding long leg short leg differentiation is masked by the explosion of snow, but checking the position of the ski tips shows that there is a significant difference compared to the turn in the second clip. Granted that the next mogul also helps to eliminate the heel push coming out of the fall line and that in general there is much less heel push on your right turns than your left turns. Nonetheless, this turn is the image that I want to see for all turns. We just have to figure out how to get there without going airborne on every turn.
There's one more turn I want you to look at: the last turn in the third clip. It ends with a smile, so I know that you know that you were caught cheating. Yes it was a wicked bump. But your lazy pole swing lets your uphill ski and hip slide forward when you need the opposite to be happening. By driving both of your knees forward before the bump,
your upper body becomes committed to going right into it. Imagine how much more stable you would have been with your upper body coming to the inside of that bump instead of smack into it. You could have been there if you had used the touch as a cue to move the hips into the new turn.
So I'd like to see you try two more things in addition to the wider stance width: changing your pole touch and ten toes. For your pole touch I want you to reach more down the fall line (away from your downhill ski) with your pole touch and I want you to imagine a string between your elbow and your hips. As you reach downhill for your touch, have that elbow pull the inside hip across the skis and forward. While you're doing this, extend the uphill ankle (not just the knee - there are a whole separate set of exercises for this). For ten toes, I want you to have more patience with your skis in the fall line. Make sure all ten toes are pointed down the fall line before you turn out of it. This attacks the problem from two sides. Using the pole touch to move the hips inside should help to allow higher edge angles to build before the fall line and reduce the need to heel push. The mental patience to stay in the fall line longer should help reduce the urge to heel push when the skis aren't turning fast enough out of the fall line (i.e. in case the pole touch thing does not help enough). The result I want to see is the hips moving more into the new turn as you come out of the fall line of the previous turn. This will reduce some of the forward flex of the new inside boot and translate that into more lateral contact and move the point of maximum edge angle closer back to the fall line. With the hips moving more laterally and a wider stance, we should also see less of an up move at turn initiation. The bottom line from these changes will be an even smoother, more efficient flow.
