I did Tae Kwon back in the day, though now I mostly practice with my sword, and I guess I have developing my own style, since I stick to traditional Iai-jitsu techniques but I use a straight blade, but I also have my own moves and such, but this is mostly because I can do some things that you cannot normally do if you are using a traditional Katana.
I'm also quite skilled in almost killing myself when I try to use my sword with my left hand, I about cut my leg deep a week ago.
I've done some basic lessons on Wing Chun, mainly concerning palm strikes and redirecting your opponent's attacks. I haven't been properly learning it or anything though, but I am more than considering doing so.
I'd also like to learn how to fight with a staff, preferably one with blades on either end.
