foot pedalling? i'm not sure if i have heard that term, or know what it means, but i am by no means an instructor.
I would say that when carving it feels like to me that i am staying centered and using my ankles to control the angle of my board to control the turn.
It feels like i am using equal pressure, but i'm not totally sure if that is what happens. Snowolf is bound to chime in here, he can be of much more help =)
