BigE, what would you say is wrong with the BAD form turn and how would you fix it?
I personally have the experiance that turns started with rotation, be it radical like I did on the video or more subtle, the fix would be counter and angulation. Counter for the reason that the skier would turn the belly button the other way, opposite way of rotation. Outwards. Upper and lower body separation. Angulation I would teach for the simple reason that the skier would stop banking and start pressuring the outside ski and to better cope with the turning forces and keep skis on edge. The turning forces are quite strong even at slow speeds like in the video.
So should I drop the word "angulation" all together and continue with "counter" only? I could change the video clip for the GOOD form to the one where I use only counter rotation for tipping the skis. Then I would stay in the axial plane.
The intention was not to display the difference between skidded and carved turns. I explained that many times alredy. I simply wanted to display how rotation affects carving in a bad way and it makes your skis skid. This is a common problem. Locking the skis into a edge locked carve in the high C is crusial for the outcome of the whole turn. If you dont nail the initiation and high C then there is no way you will be able to carve edge locked the whole turn. Much since the high C is already one third of the turn. Too little value is given to early edge engagement. That is the reason the skidded turns are so poor. They are not proper skidded turns. That would be a different discussion.
Shallow skidded turns can also be angulated. It has nothing to do with that actually.
My form on the video is to display the various movements. Its not proper skiing even though you could ski like that if you wanted. It all depends on how output you want. No input no output. I was watching some pros on the tenniscourt next to some intermediates. The difference in strokes was tremendous but those guys gave every ball serious attention and worked hard with back swing and footwork even before they hit the ball. The intermediates were just lazily hitting the ball and wondering why they never made it to wimbledon. Same applies to skiing. Also, you need to overdo all your movements in order to get a feel for them. Some times when you think that you flexing a lot you are actually not felxing any more than you normally do. Offcourse that is IMHO.

The CSIA call this axis "the rotational plane"; this axis originates at the balance point between the feet, and extends through the CM. This "plane" gives the CSIA 4 planes of movement -- vertical, fore/aft, lateral and rotational.
TDK6, what you are suggesting is that to fix an error in the rotational plane, you use movement in the lateral plane. This is simply not required, since correct movements in the rotational plane alone can do that and are a lot simpler to manage; specifically, pivotting/steering the feet.
If the video is to highlight the differences between skidded turns and carved turns, it does not do that effectively because the technique displayed in the skidded turn is so very poor.
You say that the choice is between shallow skidded turns and angulated turns. I believe that the choice is between skidded turns and edged turns. How you create the edge angles for the turn is a matter of intent, and should largely be dictated by the terrain. There is no reason that the turns you are making on such a flat pitch require such exagerrated/posed deeply angulated positions. In my opinion, form should follow function. This is not what I see in the video.
My thoughts on the movement of the hips across the skis are that such a movement is simply a lateral movement of the hips. The movement of the hips into the turn is also a lateral movement. The movement of the hips from inside the turn to above the skis is a lateral movement. Just because this happens while turning does not change the nature of the movement. The frame of reference ought to be the body and skis not the center of the turn with given radius. That is a frame that a student can understand and control.
