Sorry, can't agree with you here. The use of all rotary movements are fine. Its the degree to which you use them that may need correcting. Too much leg steering in relation to the amount of pressure and edging one uses may be a problem and might need correction. At the same time, that exact action may be the only way to ski some terrain.
It is pretty obvious that the PMTS crowd and the PSIA crowd has different terms for the same meanings. Each should "plain english" a term they use so the other group has a true understanding of that they are saying. It seems to me that when the PMTS guys discuss rotation they are really saying leg steering. Bud and VSP just pointed out that PSIA has a far broader view of what is "rotation". To me turning the torso to effect a turn at the skis has always been a rather major no-no.[quote=SLATZ]To my mind if there's turning there has to be some form of rotary motion somewhere.[/SLATZ]
Nope, there are instances where no rotation (anywhere in the body) can still result in a turn. A fully banked turn would be an example.
A note on the Phantom Move. I see this move as one that effects pressure more so than steering. Put your boots on and stand in a doorway and begin tipping (Phantom move style) and note how heavy your leg begins to feel. It seems to feel heavier the more you tip it. You are in effect moving mass to the intended turns center, as well as pressuring the outside ski. The end result is that the stance/steering (foot doing the turn) begins to come up on edge, and you naturally begin to angulate (PSIA) / counterbalance(PMTS). Phantom made simple, and it works very very well.
