Ok, here we go with some annotation....
1 2 3 4
Pics 2-4 show turn initiation with the up movement. See how both knees have straightened out and how the waist line has gotten progressively higher? The CM has moved from inside of the old turn to between the skis in pic 4. But for where the skis are in the fall line, we want the CM to be inside of the new turn by pic 4. In pic 4 you can clearly see the A frame that Bud was talking about. Notice how flat the skis are. Also notice that the feet are wider than shoulder width apart. As your feet get wider than shoulder width, they should roll up on their inside edges. But here your feet are flat. Adding canting would get your feet into the "right" position.
From pic 4, you have to step off the outside ski to keep moving your weight into the inside of the new turn. That right ski just does not want to turn yet because you've only got your weight over it in pic 5. In pic 6 you've finally gotten there and you're in relatively good position (feet are a little wide, but now we know why). Pic 1 is the same frame as pic 6, but showing the measure of angulation. 155 is a good number. You could get better by getting the hands a little more level, but you'll never get there until you get your canting straightened out.
Here the weight is in a balanced position. We can see the elbows in front of the hips, the knees and ankles flexed and snow flying off from in front of the skis. We'd like to see a little less tip lead here - hint tip lead should match counter, but this is not something I would worry about yet. The problem here is that this is where the skis start accelerating on you.
Here you can see the butt behind the heels and the left ski being raised for a left turn.
One of the things we check for is to see if the toes, knees and nose line up. The red line of the left shows almost, but not quite. The red line on the right shows a lot of body mass behind the heels. To quote my good buddy Astro: "Ruh Roh". See that hunched over back (yellow line). From this position, imagine trying to show your belly button to the wind. You've got to stand up taller and bend the knees more. This will bring the knees and the nose forward. Do you see that blue line and the 104 degree measurement? If you can get that number under 90 in this point of the turn, you'll be able to get pressure on the ski tips and get them to be doing more turning for you instead of you having to do all of the work with that ski in mid air. A lot of people get in this trouble because as the skis enter the fall line they accelerate. As the feet get ahead and the butt gets behind, the head has to lean in to stay in balance. You've got to move that belly button to keep the hips over the feet as the skis accelerate. The further you get behind, the more delay you'll have getting your skis to bite during turn initiation and the more you'll have to cheat (e.g. lifting the skis). Pic 7 shows where you need to start the belly button move.
Here you can see the butt behind the heels and the right ski being raised for a right turn. (Just to prove you've got the same thing going on in both directions)
It looks like you already got the message, but hopefully this MA helps you a little more as well as the lurkers. Oh - and if anyone has any corrections, please speak up. I'm only a level 2 and still learning.
