Re: Mixing Aikido with other martial arts
I'm relatively new posting to this board, but I've been lurking awhile. What I've seen is that there is a lot of polarization on just about any given subject: classic Aikido vs Nihon Goshin, training styles, you name it. I believe that the differences in us all allow for different perspectives. One may want to devote their whole life to one art, while another will want to sample and learn many without ever "perfecting" one.
My bottom line, have fun, do my best and hope it's just for fun.
That being said, I study Nihon Goshin Aikido 5 hours per week and mixed Japanese Jiu Jitsu (Budoshin, Aiki, etc) 2 hours a week from the same Sensei. I find that they are highly complimentary, especially as my Sensei's prime goal is good AIkido.
