it is on youtube, They also have matches where Rickson won on points; so don't count Rigan out as being a chump compared to Rickson. The guy is a beast, I did a seminar with him and it was very impressive.
That being said, I'd say Jean Jaque is the more innovative of all the brothers. Everyone I've ever talked to about him talk about him like he is a "wizard" their words not mine. Depending on your rank, body type and style (if you have one and if you are not at least a purple belt your style probably hasn't really developed) I'd just train with which ever one you could. It is just nice to train with legends like that.
