It's all good stuff Jim, I personally love to see this sort of stuff but it was a bit of a teaser imho!!
And I feel like I must add that this way of training Wing Chun is also getting more common in and around Guangzhou too with many new Sifus springing up all the time, most recently linked to Yiu Choi and others. As Joy has already pointed out, most of the earlier Fatshan and Gulao stuff is present in some Ip Man lineages and this isn't because they know anything about Pin Sun/Gulao WCK as such, it's because Ip Man had already done the work integrating it into what he taught.
The 108 Wooden Man is an excellent example of this fme.
C'mon Jim! You know I know you know the actual 'names' of these sets/movements so please share!!
Or are you saying these exercises sit outside the formal 12 hands??
