Very unlikely that the 95% of broken concepts and chi sau games that is modern wing chun is what WSL received, and that he then made the fully functional and conceptually perfect VT system out of that. It is easy to see the direction of travel from working system to broken system. .
So you think every Wing Chun lineage other than WSLVT is 95% broken concepts and chi sau games? And you wonder why you can't carry on a civil discussion with anyone else?
