Professor Murgel is a great teacher. As stated earlier he is able to break down any move so that anyone can learn it. If you have to chance to train with him than do it, you will get your money's worth.
nice lineage training under Medhi and Helio. People say medhi is a beast.
I'll have to ask about the smothies. I like Acai too, LOL.
Ground control, I have also heard that Medhi is a great instructor.
