Have to agree with Max, the right equipment can be synergistic with the right movements (and the wrong equipment can make it much more difficult to do those same movements) but skis do not make movements, skiers do. Hence if you are working and practicing the right movements you have a good chance to duplicate this. But there is no shot that a different ski will take incorrect or poor movements and make them into good movements. Unfortuantely what a lot of skis are doing today are making poor movements hold up better in difficult conditions (as in rockered tails that allow one to pivot from the back seat with a weighted tail). So many skis will allow a skier to "ski better" or survive in difficlut conditions better with movement patterns that will not hold up with traditional skis. That does not mean that the movements are better.
Which leads us all to the grand question: If the ski makes my poor movements hold up better, why shouldn't I be skiing on it?
And the answer is very simple. It really depends on how good a skier one aspires to be. As I have stated before I have worked to hard to get solid fundamental ski technique to ski on a ski that will allow me and promote technique other than that. This doesn't mean that my decision is the right one for everyone.
