zeek, once a skier has mastered the prallel turn, carving and skidding, s/he rarely, if ever, needs to or wants to do a wedge christie or slow turns on flat terrain, why should they?
It is intructors who constantly work with low level classes and who do basic turns during those classes who have the need to be able to do these maneuvers. That is why instructors are better all-around skiers than most. They may not be hot shots at the high end but can handle most everything, though I think that pro ski patrolers are the best skiers. Not technically, maybe, but all around all terrain. They sweep under the chairs with cruddy, icy and rocky conditions which most instructors would avoid like tha plague.
Lisamarie, you are a very perceptive person, quick to learn from posts here and making some lucid comments, but I don't think you have a clue of what zeek is talking about in his teaching environment. He can't, CAN'T, question individual students in his class of 15-20 beginners of what they want to learn, he has them only for ONE HOUR.
Were he to listen to fifteen students and try to remember or take notes of what they want, even in an intermediate class, the hour would be over and they would have to be excused before they even got on the hill.
Such are the realities of revolving door ski teaching, get them in, get them out.
