You said it yourself ball doing gs on icy bumps will eat you alive, that's why it's such a good challenge and takes just as much or more skill to execute as zipperline. A truely skilled skier would not look silly doing it. Your argument is like saying people that suck at zipperlines look silly doing them. You just sound so one dimensional.
I don't want to do GS in huge bumps unless I was training but it's a good mix up, nor do I want to ski with such stiffness as in moguls done in WC technique outside a set moguls course.
Huh? Your whole GS logic just sound to me like you haven't been on a serious bump run. How about you practice your GS bump turns and come on out to Mary Jane and show 'em off next year.
Disrespect? Really?? I point out the shortcomings I see in a ski instructor's skiing and that's disrespectful?
Yet it's OK for a bunch of ski instructors to disrespect an entire discipline of skiing, the world class athletes who train and compete in that discipline, and the recreational skiers who put in the time and effort to perfect the discipline?
It sure looks like a bunch of bump envy and frustration to me.
