I never got bored with riding, even on easy terrain, There was always something I couldn't do even if it was just Reuel christies or maybe someday, one footed switch arcing (with legs crossed). Before riding became boring, I discovered free-heel and snowboarding. Skiing exploded for me.
I wasn't ever very good on the traditional boards. I skied a small hill, had fun, made incremental progress, but I couldn't carve.
When I got a snowboard, I could carve turns. This was technically the best skiing I had ever done. I was snowboard skiing according to the I.D. that I had to wear showing my level of qualification (required of snowboard skiers to use the lifts and/or slopes). Meanwhile I was experiencing the worst skiing I had ever done learning the telemark turn on Karhu XCD GT waxless skis, but having fun with that too.
I considered snowboarding to be a form of skiing until recently, when I decided skiing is actually a form of snowboarding. I should have realized this when shaped skied were born and I no longer needed a traditional snowboard to carve. Still I enjoy riding one "snowboard ski".
I scarve now. The carving, well, there was a balance problem and I got tired of falling down. I carve on two boards sorta sometimes, but snowboard skiing to me now is about the flow, like you said. I let the snowboard do the turning but not riding the rails.
I let it turn, I roll from edge to edge like a drunken sailor on deck in high seas. An old cruiser who doesn't have the legs to telemark all day. An excuse to relax, play, just ride with very little effort. Even alpine skiers would be amazed at how much less effort it takes to ride one wide ski.
What do I get out of it? See my post in the "What do you get out of skiing?" thread. All that plus... The lift ticket is paid for, the workout is over, the snow is soft and wet. Fun, easy, free, pure pleasure.
