Thanks all for your replies.
I understand the point: "come and see", but that's me, I tend not to believe to my eyes if I don't understand what's going on there at all ...
Of course I'm going to visit a few dojos in my area to see what I like more, however I'm concerned with my ability to evaluate it correctly given I have zero experience. So, I'm just trying to get some basic information to know what to look at.
Wayne, while practical, self defence aspect of Aikido is not among my primary motives, as a newbie I permit to myself to be curious about that as well.
I don't want to sound stupid, but... do you consider Seidokan to be as effective as Aikikai in case of unfortunate necessity, assuming equal levels of training?
