Me? I use a pair of hockey skates and wear a pack with a few 50lb plates in it. This way I'm assured of being as "in" the snow as possible. Sometimes I'm so "in" the snow that I'm not even aware that I've been completely stationary for the past half hour. It also impresses the hell out of all the other geeks watching me from the chairlift.
What do you other experts use to get the full experience of skiing "in" or even "under" the snow?
