Re: Shioda, Tohei, and Ki Things
One reason I suggest looking at Daito ryu is because of something we've discussed before I believe...the focus on 'aiki' as opposed to just 'ki'. That seems (to me) to be the real focus in aikido's predesessor, and that is why if you want to see the basis for a lot of these things, it pays to look at what the other 'top dogs' in Daito ryu did/do. Its just a suggestion, and given the more secretive nature often associated with the higher levels in Daito ryu, not an easy thing to do in any case.
One of the benefits would be to see more of those direct applications, without the large circles of aikido.
