So left hand on the crimp, right hand undercut - I then put my right toe into the flake and rotate my right knee so it moves underneath my right arm and points left. Once you've done that you have time to pause, use the little intermediate crimp on the right and pop up for the break. The top bit after that is fine as you rock up using the ear with your right hand with your left foot on the good crimp (where your left hand was) and into a little mono-ish thing for your left hand.
