Unstoppable Chi Sau Techniques 

Production Notes: In post processing it's difficult to figure out where to cut so the clips merge together well. We started using the clacker to make an audio spike as a visual cue in the software for where to cut the film. In the beginning we were not clacking loud enough. So much to learn, good thing we started early. Each video takes about 15 mins to set up, 1/2 hour to shoot, 2 hours to put together, and 2 hours to render/transcode.

So I would train both - first have the guy release his pressure from that one hand so you can feel the hole opening (the vulnerability) and step in to tan-da, and also train the elbow pin... I'm not experienced in the chi-sau dynamics though
