Re: If you have trained in both Aikikai and Iwama, please help me...
In my experience, I've trained at some aikikai dojo which are more Iwama-like than some Iwama-style dojo I've visited in my wanderings.
My biggest criticism, my own opinion naturally, of Iwama-style is the paint-by-numbers and 'one size fits all' approach to training. But I've also seen this lack of responsiveness at many an aikikai dojo as well.
At the end of the day you have to make your training your own, then distinctions between aikikai and Iwama-style etc are no longer relevant.
