Re: No Aikido dojo - what now?? :(
I think it depends on what kind of jiujitsu it is. Alot of JJ in europe is "sport" or "technique" oriented.
If I had my choice, I'd chose Judo over JJ if that is the case. If it is of the Brazilian style, that is, a grappling based JJ, then I'd say consider it.
Frankly, I think that developing a base in Judo goes along way in learning aikido.
As someone said above, it is alot about the mindset and philosophy at first.
I lived in Germany for 4 years, and did not practice aikido, but BJJ/Grappling and it served me well in my aikido development.
