Well expressed, and as others have responded, a good reminder that the guiding principle for an instructor must be to cater to what the students want to get out of a lesson. Commonly, students' number one goal will be to have an enjoyable day on the snow. One requirement for that is being objectively and subjectively safe. What promotes that primary goal will vary from student to student. Instructors can show students options, but shouldn't elevate their own objectives over those of the students. Tip of the hat.I know that you're writing in jest but there is a serious point here. I REALLY don't like that stuff and it doesn't matter if drilling it would turn me into a Bode Miller (it wouldn't) I still won't do it. So what does that do to my learning experience?
Creates a barrier or resentment that I landed an instructor that wanted to do those balance drills again or even has me skiing out of class and asking for a refund. By all means teach me to improve my balance or relative weighting but by doing things I can do with both skis still on the ground. At least I'm telling you. The majority of people who have things forced on them in a lesson that they really don't like probably smile nicely say "great" when asked then just never take a lesson ever again.
For some, an enjoyable day would involve shooting the Chimney at S***w [? LOL] Valley. Instructors there will do that with you. That's not me.
