I have ski ranging in sidecut radius from about 70 to 13 m.
When I am carving arc-2-arc turns on any of them, I am able to carve radii of many sizes. For example on my 13 m sidecut radius skis, if I want to carve a 6 m radius, all I have to do is crank them way up on edge. Similarly the same technique at higher speeds allows me to carve 30 m radius turns on my 70 m side cut radius skis.
I have often come across "riding the side cut", and the context usually seems to indicate that the turn being made on the ski is equal to the side cut radius of the ski, which is impossible, since the ski would have to be flat to have the sidecut radius match the radius on the snow and we all know flat skis wont turn.
So like the title says,
