This flow drill utilizes applications from a number of katas including Kanku Dai, Heian Yondan, Heian Godan, Chinte and Gankaku. The uke is semi-compliant in that he covers up from attacks but does not attempt any attacks on his own. The drill teaches a means to flow into 'backup plans' when attacks fail. Not explained in the video is the throw at the end which comes from Kanku Dai. I've borrowed many of the applications shown in this video from Iain's work.
The audio is a bit rough.
