I do not know this form, but I wish I did (yes I'm the same guy who'll bash on other threads and forums with my opinion of there being a danger in having too many forms and being too focused on forms accumulation as a measure of rank over the actual application of skill through free sparring) Anyway...
I really like the fluidity displayed by this practitioner with this form. I don't see this type of movement displayed a lot in 7*
