I saw the video and used it a tiny bit myself with my monks. Basically it works off the principle that you keep casting SCK using mana until you are too low on mana and then you switch to your energy using stance. so it was something like

Both keys hit at the same time 1> 1,2

1:/cast [stance:1(or whatever mistweaver is)] spinning crane kick
2:/castsequence reset=combat windwalker stance, spinning crane kick, spinning crane kick, mistweaver


The idea is that you cast a couple of weaker, energy based SCKs while waiting to regenerate enough mana to go back into mistweaver. A sequence of four or five scks might work better between stance dances.

I haven't played a monk in eight or nine months but the concept (stupidly named as it is) of "spin to win" is sound, or at least it was then.
