Well done. You clearly understand the move and the flow. I suggest adding the Flic to the move. http://www.youtube.com/watch?v=FU1KKBIX9Ck Extremely useful addition to the move.
I actually think you have the rotation at the right level. I wouldn't change anything about the flicker you currently do except for maybe adding the flic to it. the flic is extremely easy to add so you should definitely give that a try
