Yes, visit schools near you and observe the class, pick an instructor you respect and admire. The style is irrelevant when you have an instructor which you don't have confidence in.
I want to get stronger so I can protect the people I love. Maybe I should learn martial arts. Recommend me some good martial arts and answer my question. :) thanks
