My first question is why are you stoping Akido? If you have been in it a long tiome do you need KAreate or do you simply wish to study a different art?
It might help if you said which part of North Wales you're moving to? I always thought there was an Aikido dojo in Chester? but I could be wrong there.
I know a good Shotokan teacher in Angelsea, and also a very good Shotokan dojo at the Uni in Bangor. Let me know if any of this helps and I'll find out how you can contact them.
You might want to try going to the Mona Books web-site www.monabooks.com
From there you can find contact numbers for Mike Burton.
They are one of the largest martial arts book and video distributores in Europe. Mike Burton is also a teacher of shotokan karate-do.
Good luck,
Mike
