Flexion and extension and their timing:
Get as low as you can possibly get ( make it hurt a little) and retract the front leg as you shift forward. Extend through apex to increase edge pressure then as you shift aft, retract that rear leg to get low through completion.
I think I get everything except this. I guess the question is, how do you down unweight for the edge change if you are already low at the completion of the turn?
