Hmmm at the risk of getting shot in the cross fire I would say this. The original post was about information about wing chun. And I definately think it is a good art and worthwhile taking it. Again it may be halpful to know who the Sifu would be and the location to get a more accurate assessment of the Kwoon.
I think every practicioner should have a reality based mentaility and challenge what they learn. Regarding, bone breaking, dislocations, hyperextensions yes it can be done, especilly if they teach chin na. But just like judo JJ HKD we train for it and you feel the hyperextension with minimal effort. could it work in reality yes, but it depends on factors. My first thoughts would not be break bones in fingers, feet, arm rib, mandable (actually this would be a KO hopfully

). It would depend on how escalated the fight is. Usually the breaks are setup after a series of moves, its noty like the matrix, touch arm breaks. So I do agree WC has the ability in the system and in reality but I hate say it but it depends on the person.
The average person really does not have the eye of the tiger so showing these techniques in any style would be worthless if the practioner feels they are extreme.
on that note you guys may resume.
