In my humble opinion (well it probaly isn't that humble hehehe) If what you have works and you are happy with it, another energy system(let alone 300+) or varients of the one that you have is going to make it work any better , or you be any happier with it.
Reiki, as we practice it was developed over a few years by a man who studied for many years (allegedly) and not channelled from long forgotton races on this planet or from aliens.
My feelings are that you develop what you have. Most of the best healers I have met just have the one system or possibley 2 at most.
I do think that if you have to many different systems, that it tends to confuse your energy. Think of if you are in a room with 300 people, and they are all talking to you at the same time, all telling you to do something different. What effect would that have?
