I don’t understand this modern concept of that’s not wing Chun if you add this or that...a Wing Chun or JKD channel I like on YouTube named Adam Chan, he mentioned how Wing Chun guys would test and adapt the art, one guy fought and beat a boxer and adapted a lot 9f boxing...I believe Bruce Lee did that too.
As the OP said lot of the issues with wing Chun schools are that there’s no conditioning or as you said no adaptation. Another channel On YouTube that’s great is Philip Hartshorn, his Sifu has a channel too, Russ Cichon
I don’t dislike Rokas but I also don’t see who he or guys like Ramsay dewy are to act as though they are the judge and jury of the MA world.
