I'm curious how the light touch training was presented. I find that the maintaining connection aspect is often overlooked. I once had Harvey Konigsberg teach an exercise where uke was asked to just barely touch and nage had to create the connection to move him (Harvey scolded me for following his movements and then went on to move me in such a way that made it impossible for me to let go of him). I found this type of connection very hard to establish, and event though it's been a couple of years, I still think a lot about that exercise. Probably learned more from it than from any of the "aikido techniques" we did that day. Of course, such an exercise is useless if uke follows nage of his own free will.
I agree that connection aspect is overlloked. Such exercises can be done efficienlty, if they are immediatly followed by the applications of this concept in actual techniques. Otherwise, it is as a teaching how to swimm in empty pool.
I'll show you 'light touch training ' next time we meet.May be at May seminar?
