This was my advice to learn to get her moving centered and then applying balance skills to the evolving parallel skiing. Running the balance drills through wedging seemed less useful when a bit of work slipping and steering can get her matching and ready to layer tasks up on it.
This was exactly my reasoning for starting with Basic Edging DVD and I always planned to go back to Basic Balance drills as soon as I can do the basic steered parallel turns.

I completely agree with others about these DVDs being the most comprehensive and systematic learning tool available.

Thanks everyone for all your input.
