Dpkuro, I am happy you are training hard. That is the real spirit of a martial artist and I am sure you have the potential to become a great warrior if you keep up the good job.
Karate is a nice martial art too, although is does not include joint manipulation and throws. In the Genbukan we do also study Karate, although its another style called Koryu Karate. We also study Chuugoku kenpo (Chinese martial arts) that include Pa-Kua. The Genbukan Ninpo system is pretty much the most complete martial arts system I've come across ^^
