Jim, I was thinking about the bottom turn in my first post. If I understood you correctly, you meant that although the bottom turn looks like a carved turn on snow, the technique involved in doing it is different in some way which is hard to describe.
Actually, I was hoping for an answer of the type: "It's almost the same; just do X instead of Y". This was maybe unrealistic, since it is often hard to describe the technique that one has learned by doing.
I will go on experimenting with the turning, until I nail the bottom turn. Hopefully I will have a better understanding of the matter in a few weeks :D
Thanks to everyone for your answers,
Henkku
