That's wierd- I was just daydreaming yesterday about the differences and similarities in my old water slalom days and the carving I now do on the mountain. Was wondering how I could turn so well on the ski with no binding angle (or 90 degrees, in snow terms), and whether it was possible to board without an angle, or practical/possible to waterski with angles like snowboards. I'm no physics whiz, but do wonder if one could learn from the other??? Come to think of it, I'm really no carving wonder-boy either.
I know (and remember) just enough to be dangerous.
