Hey, ma cherie. Yeah, I was pretty happy to see her back as well (go figure, huh?). With regard to the forum formatting, some good things, some that need a bit of getting used to, but I don't think Bob has finished tweaking it yet.
Easy, Wado Ryu, sometimes considered a branch of Shinto Yoshin Ryu Jujutsu, it's easily the most circular karate system, and quite a bit of kata involved as well. As there is a higher emphasis on grappling you'll find it more comfortable to go to from your background.
Ah, you beat me to contact by a mere day or two! Yes, I've been rather busy of late, and it seems to be getting more and more stacked... but you shall hear from me again, never fear of that! We shall figure our way around this turning globe, pulling in directions near and far, giving way to closeness even at a distance..... or just catch up on facebook!
As they say, though, the right tool for the job.... Okay, okay. Let's look at this objectively, yeah? Can't kill them, they're already dead. Won't feel pain. But you can stop them chasing you... if the legs cannot support their weight, doesn't matter if they feel it or not, so take out the knees and ankles. As they fall, grab an arm and use an ogyaku shoulder lock to drive them face-down. Then we get the sharp pointy things. Okay?
