i'm not opposed to one legged skiing as a skill much like i'm not opposed to advil as a drug. advil may or may not cure a headache and it has known side effects such as stomach irritation and or liver damage if taken in the wrong dose.
again i'll reiterate it was vis a vis the instructor describing potential pros and cons. if done with the skill focus you have outlined......."the amount of movement required for edge change." well then there is a pro.
i presume examiners in the nrm division are looking to see if the movement required in the task is done sans any upper body rotation.
nolo, i know you are fond of Horst Abraham who wrote the following in "ATM Teaching Concepts"; "When executing braquage with the legs comfortably apart, the movement is strong and versatile in the sense that it can de done slowly, rapidly, intermittently, or all at once. As soon as the skier closes his stance, or stands on only one foot, the mechanics change insofar as rotation or counter-rotation of the entire body take over"
again quoting Bob Barnes in "The Complete Encyclopedia of Skiing";
"Upper body mechanisms can pivot the skis, but they cannot steer them", hence, if you agree that standing on one leg requires whole body or rotation/counter then i would question whether skiing on one leg can demonstrate steering of the inside leg as mentioned in the NRM skills focus.
BTW other divisions include one legged skiing in their exams. The Rocky Mountain division does not. i have always assumed it is included in exams for a two fold purpose. to see if exam participants can isolate tipping or edging movements of the ski without rotational movements of the upper body.
if an instructor feels as though one legged skiing is the be all/end all in terms of drills or exercises with no down side then i respectfully disagree. the potential for rotation/counter-rotation is the potential complication. it's the stomach ache side effect of advil.
perhaps "run don't walk" to get another instructor is a bit harsh.
i'll soften that to hop on one leg
