How effective is the Berimbolo ? I see a lot of guys in GI use it, but not in noGI, and MMA. I always wanted to try and train it. I am pretty flexible when it comes to doing granby rolls, and I've searched up some videos online by Stephen Kesting. Any of you guys recommend training this move against bigger guys ? If not, what alternatives do you use against standing guys who posture up different(90 degree bent forward, standing tall, sprawling back pressuring you down? ) Anti guard player here! Hehe!
