These two clips where posted in another thread and it struck me as a great example of "how you ski, is how you ski." You can see that this skier uses the same turning style, or "skill set" on the groomed, and on the bumps...guarnteed he does the same in powder, long turn, short turns...etc etc. People dont use skills on one set of terrain and then stop using them somewhere else...or miracuously have them appear somewhere else. These clips show that beautfully.
Hence next time taking a lesson...keep this in mind. Just because, for example, you may not have actually skied powder, or bumps...doesnt mean you werent improving your bump or powder skiing. Hopefully these clips make it easy to see how improvments in his short turns on groomed would carry across to bumps...and vice versa.
Hence it is not you cant ski bumps or powder etc....it is the holes in your technqiue just get shown up more as the terrain becomes more difficult, or your speed increases or what have you. It is pretty easy to see here, unsurprisingly the short turns this skier has on the groomed, are what he has in the bumps...with all the benefits...and drawbacks...his technque or "skill set" bring.
