Powder is a different ballgame. You can break the rules on a 3 ft pow day, look at Shane McConkey. I do agree it takes fundamentals to be able to ski it efficiently but I also think equipment being dialed for conditions comes into play more the deeper the snow is.
You do see that 'dialed for conditions' really means 'dialed to *you* for conditions', yeh? So that if you have an immensely adaptive *you*, the dialing doesn't need to be so narrow?
