It's established that solo training to develop aiki has been done in Daito-ryu (by Sagawa and others) and aikido (by Ueshiba [who was an exemplary Daito-ryu practitioner] and Tohei in particular). So, isn't it reasonable to say that if Tohei was devoted to aikido, and Ueshiba (if not his son so much) seemed to acknowledge the approach and value of what Tohei was doing, then Tohei was combining the Daito-ryu-based approach he learned from Ueshiba with shin shin toitsu methods?
