I am going to visit an internal school in the near future and would like to know if there are any tell-tale signs that i should look for that reveal the teacher to be combat effective. I dont want to just walk up and smack him in the face yelling "Bring it bi tch!" so anything would help. I really want to devote alot of time to an internal art but not if the guy doesnt know the combative aspect. Thanks in advance.
