Don't see why you can't link WP turns. Didn't the Mahres do that in slaloms?
Actually... you can. WPT's are awkward in the form that the Mahres used, but if you think about it, the difference between a Whitepass turn and a "normal" turn is that the outside ski is pressured
much later in the turn. But as the Mahres have demonstrated they can be quite effective in certain situations. Not to digress too much from the original intent of the thread, if you think about it, it has MAJOR implications for when and how pressure is applied to the outside ski in "normal" skiing. To the untrained eye it looks simultaneous, but it's not quite. And while I keep both skis on or close to the ground most of the time, my pressure transfer is both subtle and deliberate. I keep a variation of it in my head when I ski. All I do differently is pressure the outside ski very early in the turn (but sometimes a bit later), rather than late as in a WP race-type turn. Essentially, I use a dumbed down model of the WPT with early pressure transfer and more moderate body position and appropriate flexion/extension.
If you use the Whitepass turn as the extreme model, you don't pressure the outside ski at the beginning of the turn. But in modified form you can allow pressure at any time during the turn. It is the most versatile application of natural forces that I am aware of in skiing. It's just a matter of timing, lateral body position + flexion/extension of the legs. The WPT is an excellent tool to help understand how to direct body position and helps get a grasp on how the inside ski should function. As you all know, an arc is no more that direction change, and when the skis change their direction in the path of a turn, the mass of the body is affected by momentum and centrifugal/centripetal forces. So the combination of timing and directing one's mass in concert with active flexion and extension add a lot more colors to the "turn palette" than many recognize. [I'm not a very good proof reader, so I'm sure I made some blunders or omissions in my descriptions. I think I already made three or four edits on this for clarity. Feel free to call me on them. ]
BTW... For those just getting into skiing and are hooked, I highly recommend getting hold of Warren Witherell's two books- "How the Racers Ski", and "The Athletic Skier". Tons of insight in both books.
