Here goes someone in my family in NYC.

He is of Augustine Fong lineage (Ho Kam Ming), and GM Fong is my sibok. I have personally touched hands with GM Fong at a seminar last year. He is definately skilled and I got a chance to work out with a lot of his intermediate and senior students down in Tucson, AZ. They were all nice people and all had some skills.
Now, for Sifu Grados, never met him personally, but I met his sifu, and have nothing but good things to say about him.
