well I idk know about grete but this thread has been entertaining. as far as sarah is concerned she is a bit cocky and her style is kind of sloppy. she needs to clean up some tricks, be a bit smoother, and hold grabs for longer. but she is still a good park skier and deserves some credit, but not that much.
and I'm sure roxy will make a big mountain ski sooner or later, I saw the rep at alta, but then again she was wearing really nice furry snowboots, so maybe not....
