Yeah kaeshiwaza is a good example of what I was talking about. When we do empty handed freeplay where 2 individuals (there is not really an Uke and Tori in this case) are equally attempting techniques, it aids in not utilising too much muscular force to resist a technique but instead move with it, constantly adapting and using the changes in motion to assist your own technique.
I spoke to Kendo Eddy a few days ago and he mentioned speaking with you. He's eager to get in some Kendo when you're here next. Of course my dojo door is always open to you. Maybe we can get Eddy to do some Aiki and I can try out some Kendo.
I'm happy things are going well with you and your training.
