Personally, he is a great guy. Very gracious, very kind, always makes everyone feel welcome and like he has known them for a long time.
In terms of his teaching and his jiu-jitsu, I basically echo what Balto said. His style works very well for some people, and not very well for others. It is very much a->b->c->d, almost robotic. You screw up at c you go back to a and go over again..
Some people need to learn that way, and a lot of people do well like that. However for me, I can't stand that style. I think it stifles creativity and goes against the heart of bjj. For example, every pedro guy I have gone against always goes for the same 1,2,3 techniques from the guard. Some of them are very good at it, dont get me wrong. But its all the same - Start with the collar choke, try the armbar, try the sweep, etc.
Its not a bad sequence, but I don't think all of your students should be doing the same thing. Thats a bad sign imo.
and of course the issue of stripe and belt tests and fees. I think its inexcusable and simply a money making ploy. At the Pedro school I used to train at people had to buy the dvds to learn the techniques for the test. I have been corrected and people told me he doesnt do that anymore.
Still - charging a belt/stripe fee is nothing more than a money maker, and I disagree with that.
