O'sensei was fine with new ideas and changes/improvements to Aikido. However, I don't think we can stray too far off the road that he established to be called traditional. Mixing Aikido with Monkey Kung Fu won't be considered traditional.
Teehee. I have Paulie Zink's (a putative but INCREDIBLY flexible monkey kung fu master) very own autograph in my yudansha book. You think anyone will care his name is in there for my next grading? I figure it is MY record of MY training, and I enjoyed the crap out of his visit. He said my horse stance was good as he jumped up onto my thighs. Holy crap........
