I'm not a huge hapkido fan. I did it for a year, but it can't replace jiujitsu and judo as my true loves. I even liked aikido better. And kickboxing.

But, the main thing is do something that you will enjoy doing. Go watch a class and see if you like the students and the instructor. If you like hanging with them, do it! If they are freaks that will drive you insane, don't do it - you've already got your blinvisible friends for that!
