I've gone down that road. I'd do it again, but I have very specific schools I'd try. Not boxing, not taekwondo, and really not anything that focuses on contact, power, and breaking. I already know how to do that pretty well. I would however love how to redirect energy like you do in Aikido. Something indirect, circular. I can cripple people. Now I'd like to be able to control a fight without hurting my opponent. Or hurting them to a minimum.
