Hey how come everyone is all caught up on what is what and whose is better (no offense). There are two fundamental ways that you would want to learn ninjutsu: you either want to become a ninja like in the old days of Japan (the weird thing is im black) or you want to learn it for self defense. Most people want do it to learn how to defend themself which is alright. now if Traditional was translated and taught by the japanese in the mountains an in that terrain then there training, if taught the exact same way all the way in to the present, would be extremely piontless and hard to adapt unless he lived on the concrete. Then there is the modern, which is weird because ninjutsu is not new, but what ever, then they have incorporated the rule of concrete, so if there aint no trees around then what you gonna do, which is the stuff of today then there "version" of ninjutsu would be more "concrete" happy, ya know. If you jump off a 11 or twelve foot branch into the street or on hard ground ya'll know what i mean. Let me know what you think okay. No arguements singling people out pleeease.
