I have to say i had a few problems with GKR at first. But now we have had a new Sensei turn up and he is really changing things around. He’s shaping things up and i was in class with him for 5 min and he had corrected me on 3 things and im like wow he’s good. He’s making the classes better and finding the problems and correcting it or getting rid of it full stop. The problems with B/W belt is some are not that high them self’s. He doesn’t like it so he is giving them a choice come to my senior class, and he will train you to destruction till u r worthy of that belt of he will give you your old colored belt back. He wants to lower the amount of B/W as he see to mainy in class domonating towards the students. And generally make it a joy to train not a chure. B/W = Black and White
