The best reason to move from one art to another: that green, green grass.

I think your questions can better be answered by the Aikido Federation of South Africa (http://www.aikido.org.za/afsa.asp
) or another such organization (if there is one).
In your "Hi from South Africa" introductory post you said you've studied a little aikido and Daito Ryu over the last several years. Enough, perhaps, to understand that while aikido is descended from jujutsu and, to a beginner, seems to be a soft form of jujutsu, it is really a different martial art. So, to learn aikido, you need to join a dojo as a beginner and gradually learn the difference.
