truuuu.  if you wanna be "good" at skiing in the eyes of the public, learn backflips.  dont even worry about spins, rails, or any form of cork.  Tell a "normal person" you did a double cork 1080, and their response will be "...."     however, tell them you landed a BACKFLIP and they will get all excited and say something along the lines of "whoa, youre really good!"  haha
