I am interested in silat. I have the Bob Orlando book, and it is very good. I also like Marc MacYoung, and he highly recommends silat as a practical self-defense/street martial art. My real question is, what is with all the various versions ? There is a silat school in the city where I live, and I will probably take lessons there. But is the style important ? For example, I have heard that there is "Dutch silat", etc. I would appreciate your input, as I don't know much about silat. Thanks.
