I would probably go for Jiu-Jitsu, but I would also like to try out a weapons martial art.

It would definitely be jujitsu.

Well since I have Shotokan for standing, and Judo for clinch (and some ground), I'd probably go with Jujitsu for more focus on ground. I also think Kendo would be cool, and I hear it is similar to Shotokan in some ways (the rhythm and such).

I would say judo or jujitsu to have more options on the ground if a fight gets there (not that I expect to be in too many fights...). It just seems like it'd be a good compliment. Although it would be fun to study Kung Fu or Baguazhang or even Tai Chi at some point (with a defense focus and not just like a dance like most people treat it) just because it's just so different than Karate it'd be interesting to see the different techniques and be able to suppliment what I learn from Karate with such a different style.

Definitely Judo would be my first pick, though Escrima would be my second.

I do judo and love it, if you get a chance I highly recommend it.

I do judo and tkd I would like to do either jujitsu, whether its gi or no gi. I use to do some boxing and would like to do it again.

I'm seriously tempted to try Tai Chi... or some kind of movement-centric martial art, but I've no clue where to find THAT kind of thing.

Problem I found with Tai Chi is that you have to look hard to find a teacher who isn't just teaching it as a recreational activity as opposed to martial art.

What exactly do you mean by 'movement-centric'?

Something that focuses on evasion and movement. Like Ba Gua or some other chinese art. To contrast with and complement my Shotokan which has more of a focus on strong stances and power.
