saw he had a great teaching style. He introduced the topic of kimura trap / arm bar with great detail and walked around helping anybody who needed a hand.

I tell this story all the time, but when I was in the Barnes & Noble martial arts section a couple years ago, this dude who also trained was browsing and we started talking about BJJ obviously. He was like, forget everything else here, just get Guerrilla Jiujitsu by Dave Camarillo. After the seminar I see what he was talking about.
