There is YM VT (based exclusively upon pole and knives). There is pole elsewhere. There is not hand only prehistoric VT style. So you are wrong (again).
Uh, no. Sorry. You logic is obviously flawed. No one would expect there to be a "prehistoric" VT style still around. Its the whole "theory of evolution" argument. Haven't you been following this thread??? But there is NO system of Wing Chun independent of WSLVT that teaches the "empty hands come entirely from weapons" theory and that tracks the empty hand and weapons so closely together. THAT is a much bigger problem that there being no present day "prehistoric" VT style!
