Re: can aikido benefit from chinese arts?
Interesting feed-back. I'd certainly say suburi has increased hand-centre coordination and ability to drop the centre. Also, I have heard of problems of people incorrectly using internal practises (a friend had kidney trouble after doing chi-gung one time, and the alternative therapist spotted it immediately); generally you need a very skilled teacher.
As an aside - I have been reading the tai-chi classics, and if there was ever anything that was appropriate to aikido it is these.
