Kenpo is generally well rounded, or atleast I d like to think so, however, it is a striking art mainly. I cant really say that Kenpo is a United Art, there are many different variations of the same system and different systems of Kenpo that have evolved over the years, there are also a lot of different organizations within same systems of Kenpo. I will focus on Ed Parker's American Kenpo (EPAK) because that is what I studied. There can be different variations of the same technique depending on your lineage, for example, while in some schools a certain technique may be taught with a hammer fist, in others it may be taught with a grab, in the end however all roads lead home. The belt requirements may also vary, some schools teach a 16 technique per belt curriculum, while others (like the one I practiced in) teach a 24 technique per belt curriculum. There are also several organizations that have flourished within the EPAK community, some very legit, and some not so legit unfortunately. I hope this helps you. If you are interested in a Kenpo school around your area you can post questions here and there may be someone that can tell you whether they have heard of the individual or not. I hope this helps you a bit.
