Aikido Sangenkai has a great bunch of people training together not to mention the absolute goldmine of translations provided by Chris Li in his blog; any person serious in investigating aiki and internal arts should check out the articles here!
Kristoffer and Matei are first class martial artists and great people to boot; if you're in the vicinity of Oslo I can't recommend enough getting in touch with them to train.
Mika had been training in Sangenkai methods for many years and can be relied upon for great training, get in touch if you're planning on being in Sweden anytime.
The Spanish group are a lovely group to train with and you'll find a number of dedicated practitioners from several martial arts who are putting in serious work on the material; they're also lovely people who enjoy good fun, food and drinks outside of training.
