Isn't this the epitome of a strawman argument, Joe? Who have you ever met who thought that they were "invincible" just because they "knock about with Japanese type gear and spend time doing fancy throws"? And, honestly, hasn't this particular strawman been just about beat to death in this forum? You're picking a fight with no opponent.
Picking a fight with no opponent is preferable to picking a fight with an opponent. I think this question about the effectiveness has been done to death.If so why is the subject being discussed again? Can't we think of better things to discuss herein? Cheers, Joe.
