I've never been much of a seminar goer myself. You can easily chalk that up to a nicely formed combination of cheapassedness and a bizarre Jiu Jitsu stubbornness. It's led to my unique style consisting primary of about 4 "go to" moves and the sad inability to explain some basic fundamentals to beginners.
Damn, I need to hit of some seminars. Jokes aside, this is a terrific highlight video of a recent seminar Ryan held in Liverpool (that's in England). The guy has mad style on the mat and he works that stuff in competition. Solid.
