I'm interested in learning a practical art that would be good in self-defense situations. As a kid, I did Tae kwon do for almost a decade, but it wasn't what I was looking for (too sporty, not really practical for defense.) I wrestled in high school, and have been doing some Jujutsu as well, but want to learn things practical in more situations (on the ground Jujutsu's great, but I want something more encompassing.) I've been looking around, and ninjutsu came up. Would Ninjutsu teach me enough practical things to be a competent self defender? Also, I was wondering if, in terms of how well it would prepare you for self defense, there was a significant difference in the styles. Input from anyone who's either trained under multiple styles or has any positive or negative views on self defense applications of Bujinkan, Genbukan or Jinenkan would be greatly appreciated.
