And I could go on and on...you'd be better off researching grapplers who's styles are similar to what you want to be and search for their material. I'd start with the Gracie Jiu Jitsu...get your basics solid, then slowly work your way into 10th Planet, Wrestling Concepts and whatever peaks your interests, but never underestimate the basics. Roger Gracie is the best Jiu Jitsu player in the world because he keeps it simple and hangs on to dominant position when it presents itself and he goes for the kill when it's secure (and he's been repping his stuff since he was a baby), but you probably already know that...you're Gracie Barra!!!
