Brian:
I'm not familiar with R.A.D. terminology, but in the B+ I am learning, I think that the preparatory position for the back foot is full tendue derriere. It did feel like full pointe, although that was probably due to my error in not keeping all of my weight on my supporting leg.
I am the only guy in this class, which might factor into it. The instructor seems to be sensitive to this, but lately she's been dropping strong hints about pointe work, which everyone else is pretty enthusiastic about. I'm having none of it, though.[/i]
