One interesting thing is that when you look at other styles - indeed just looking at different instructors within the same style - it is the things that are the *same* that really show what "Aikido" is. Differences seem to be on those things that aren't really core.
I also agree with Janet...a large percentage of the difference between styles seems to be the teaching methodology. That's my usual answer when people ask me what's the difference between Yoshinkan and other styles.
A word of warning...since you study Yoshinkan (and presumably are not way up there in rank yet) many people in other styles of Aikido will see your Aikido and think of it as robotic. Not a problem...its a function of the teaching methodology. Just thought you might like to know.
Of course, its not polite to look back at them and say things like "you look like your always about to fall over". Keep those thoughts inside and follow what the instructor at the dojo you are visiting is doing...
PS...please give my regards to Mori Sensei. He was one of my teachers at hombu before he left for Australia. And one of my students is heading down to see you guys soon for a demonstration sometime in the not so distant future.
