If you can't find a good KM school I'd say look for a good, old fashioned boxing gym.
Reminds me of my karate instructor telling us once that a professional boxer would defeat a karate practitioner. This was MANY years ago, so I'm not sure of the basis for his statement, but it may have been based on the boxer's superior hand speed. If it wasn't hand speed, it was something to do with footwork and balance. The memory fails me. Anybody here enlighten me?
