First few chapters and a few videos on youtube. Before you give more advice, go read the first few chapters of bobo and a few videos on youtube and tell me how, at all, can that define your style at all? And DEPENDING on style, you may want to learn those old routines in bobo, OR, newer routines in newer books, depending on style. Even after that, you have to understand that entertaining back then is NOT the same as entertaining now. So EVEN if he wants the older style, he is still going to want to learn newer techniques in order to actually entertain the people of today. Every coin pro started in bobo? Really now? Ok.
