I am confused. Last year I took private lessons at Vail for three days with the intent to learn mogul skiing. My instructor taught me to not ski in the back seat (a very good tip) and how to carve properly. Both techniques I am glad I learned. But when we got to the mogul field, he wanted me to continue skiing the way I was skiing on the flats, mainly carving using my hips to initiate the turn and moving my hips to the inside of the turn. I stuggled. This year I decided to check out the internet for other ideas about why I couldn't ski moguls. I came upon the "stacked" technique of skiing moguls, using your knees to initiate the turn and keeping your hips over your feet (downhill ski).
Why is there such a discrepancy? I was told that the PSIA does not teach the "stacked" aproach. Why not? Am I risking injury by using the stacked method.
