vt guy,
The information on Master Lewadny's website is correct. He is a very skilled Wing Chun Master, and did learn "Cheung" style Wing Chun in 8months back in 1986-87, as he already had learned Wong Shun Leung style Wing Chun in the seventies. Since there are genius’s in every field, I would consider him one of these types of people when it comes to martial arts. He trained 8 to 10 hrs a day for the 8 months that he trained at William Cheung's academy in Australia and he has certification from GM Cheung as a full instructor (Sifu of the art). What is taught by Master Lewadny is a combination of the Soft (Cheung style) and Hard (Wong style) at the schools under his association, Canadian Wing Chun Kung Fu Association. Master Lewadny is also a certified instructor in the Butterfly and Hung Gar systems of Kung-Fu. Your best bet is to go down to his school in Calgary and check it out for yourself.
