Really Sifu Al and his wife Sifu Milia were good clean tourney competitors and his inovation was unique for its day. He basic took existing concepts of his trainning and combined them. Watching him spar he looked mostly Northern kung-fu, he took anything that he thought that was good and effective or pretty. Their son Mark is a movie star he played in the TV series the Crow, Capiero the movie and others. Though these guys can do each art they don't seem to flow into each they cut it on and cut it off, Like I use to do, not good. I haven't seen it (the style) in a while it could have evolved. I hear it had a big following in Europe and USA.
He is real and innovative for his day.
