Here is another bunkai clip for a sequence out of Bassai Dai. It isn't very elegant and I'm not a big fan of overly complex applications as the effectiveness can be hindered in a live scenario. At any rate I hope you find this one interesting. The head crank was inspired by some of the work I've seen and done with Iain at his seminars . I believe there are a lot commonalities among kata given that humans only have two arms, two legs and a head and there's only so many ways to crank a neck.
