Last thing if anyone teaches you something called "the falling leaf" get your money back.
I would agree with that, I tried it quite a bit and got nothing out of it. What worked for me was getting on a really flat bunny hill and traversing the hill keeping my board almost flat until I wanted to turn then engaging a toe or heel turn. I took up a lot of the hill doing this but it gave me the basic mechanics of turning and now I take up very litte of the hill.
I am still a newb but have progressed quite well with a lesson and plan a few more this coming season.
