Ahh, so slopes grades are a bit different but the type of snow is what makes the biggest difference.
Here on the east coast there is usually 3-5 inches of powder/grandual followed by hardpack/ice. I am handling blacks here pretty easily. Just not to sure if I can handle west coast blacks, but I will slowly move into them when I get out there this winter.
The thing I hate the most on the east coast are the hard mounds, not quite moguls, that develop on the slopes either from skiers or just terrain. I hate when it tosses the board around enough till I bust my ass.
