Is TDK the best fighting style of self defense for street fights?
Depends. In general I would say no (and I practice TKD). But if you find a school that will teach it as a self defense art, you might do okay. I don’t mean style (WTF, ITF, ATA). I mean practical application. It’s nice to know fancy kicks, but you need to know when not to use them. And it’s not really all that great for multiple opponents. Few MA’s are though in my opinion. Personally, I found a school that taught TKD as a primary art, with a lot of Hapkido as a back up. So I feel a little better about the self defense aspect of my training. Not enough to screw with a gang of Hell’s Angels, but a little better none the less. And don’t forget to try it if it’s what YOU really want. It’s not like you can’t switch later if it doesn’t work for you. It would at least get you started in a striking art, which could be better than nothing. Best of luck to you.
