I must agree Teach i'd love to see a demonstration of the TMG waggle. I've looked at all the gallery videos but to my knowledge i didn't see it performed once.
I posted about it a while back and had it explained to me but i still don't really understand it, it seems such an awkward action to perform over the ball. I think it's one of those things that need to be seen to be understood.
For now i'm just sticking with my normal waggle, whether it encourages flipping or not i feel i have to do something to keep my wrists loose.
