you nailed it. my brother and i were sparring and we decided to get a little bit harder for a lack of a better word we put on a helmet and began to move around i caught him in my blast and i ko him. now he is 5'10" 300lbs and fairly solid.i am not arguing that i or the straight blast is superior to anything just it works best for me. paul vunak is a bad man and his teachings are just that end the fight before your OP has a chance to display their skill.i trained under dave durch who was a student of paul vunak and i may be a little bias <spelling>
