Plus I can't imagine here in the states having a school allow you to come in and test them if they have no clue who you are or where your coming from. Just because someone comes in and says they are BJJ doesn't mean squat. Unless your familar with the person or school, no ones going to let you roll if for no other reason than liability. And it would be a no win situation if you came in all arrogant and challenging, you win? Well you probably were supposed to, if you lose? You'd never live it down in your own MA world. Worry about your own training and we'll worry about ours.
