Though I'm not a member of Tomiki school,
I think that randori and competition system
is quite good and reasonable. I think, in that system, one can see his/her technical
problems with ease. I see that some aikikai
people tend to believe that they can do
everything without any doubt. Of course,
tomiki students shouldn't concentrate
on 'win' itself.
ps.
One of my teachers is also from Sheffield.
