Having an online MA tutorial would be wonderful.
Over the last two seasons I've had the pleasure of working with Bob Barnes in his evening MA training sessions and would love to see him "guide" but not own such a thread. He has enough on his plate.
I would strongly support a process similar to the Bob's MA training in that we need in the early stages to establish a fundamental understanding of the basic mechanical underpinnings of good skiing. From there you can begin to recognize differences, the impact of those differences and then address possible solutions. You hit it on the head -cause and effect. As all of us who have done clinics know there is a tendancy of many, both instructors and general public, to address symptoms and not root causes.
I do agree with the thought we need to see both "good" and "bad". I believe that will provide a great educational tool.
Getting video available could be a problem just because of the download times, as proved in the MA threads I put out earlier this summer. Maybe somebody knows an easier way.
Now, if somebody could tell me why I can't play in a golf tournament where I don't get clobbered by lightening, hail, torrential rain. high winds, cold, ash from forest fires, etc.,etc. I'll be a happy camper. I'm 5 for 5 this season-must be bad karma.
