Id have to say judo also...judo is a defensive type of art, and i would only want to use it to disuade the attacker, not put my hand in his adominal area and pull out his spleen (this is just sarcasim, i dont think you can de-spleen someone..or can you?)
Can you imagine what the posts would be like..if you switched the location of the i in martial arts? (marital...lol)
