Add 'Mastering The Rubber Guard' by Eddie Bravo. It's very different than any martial art book I've read. It delves into Eddie's personal philosophies not only on jiu-jitsu, but other facets of life and he shows how they are both intimately intertwined. The techniques presented flow logically and are different then anything else you will find. It is much better than Eddie's prior project, 'Jiu-jitsu Unleashed'
