Karate, Wing Chun, and a soft chinese art, Leihai Wishi Quanfa. Had to unlearn it all (except for front and side kicks from karate) for boxing and later MMA. Boxing kills them all in terms of effectiveness. Not at my level, but a competent boxer will smash ous literally before they know whats happening. Karate was by far the most useless in a real fight, except for the basic blocks and kicks. Punching technique is just a joke.
