Koichi Tohei is perhaps the most notable of O’Sensei’s students, being his first 10th Dan. There are numerous accounts from the other shihans of Tohei’s strength and ability. He was also, I suspect, the pit bull that O’Sensei would sic on visitors who wanted to know if Aikido was “real” or not. He was famous for teaching a particular set of 50 techniques. I list them here in the order that they appear in his bookAikido: The Coordination of Mind and Body. In my own time, I am comparing the techniques and their execution to others such as O’Sensei, Morihiro Saito, Gozo Shioda, Shoji Nishio, Yoshimitsu Yamada, and Christian Tissier, and my own daily practice. Perhaps you might do the same and see what you come up with.
