I have found that every martial art that I have encountered has similarities in some form or another with Kenpo. All of them are just variations on theme. They may be emphasizing something that you may not see in your normal training but, the fact that a lot of those techinques or principles fit almost seamlessly into the curriculum is somthing that I have found to be very encouraging.
IMHO, I have that all the martial arts that I have been exposed to are all from generally the same language, it is only the dialect that varies.
