Thanks for all the great replies to my post. I'm thinking that I will stay with just Aikido for now. To be honest, I live in a smaller town that doesn't have too many arts anyway. Mostly kung-fu and karate, with the odd jujitsu and of course aikido. I was considering taking jujitsu, but given how similar that is to aikido, I would probably have to stop taking the latter. And I'm not sure I want to do that...
