Re: yet another annoying cross training q
I agree with Ron on the main point he made - look for the art that has a competitive form of randori. I am using the word competitive broadly, not simply in a sports context. In aikido randori, uke attacks and nage counters the attack with an aikido movement. In judo, the uke/nage distinction is meaningless. Both people have the opportunity to be uke and/or nage based on what happens. It is a whole different ballgame when you are not only trying to throw a reluctant training partner but the partner is trying to do the same to you at the same time. I do not know if Danzan Ryu Jujitsu has this but it would be the thing I watch for most. I cross train with taihojutsu, a combination of judo, kendo and other things thrown in that is used by Japanese police forces. My sensei is explicit that the free practice of judo and kendo is a big reason why he teaches both.
