Any Judo/Jujutsu History Question?

It looks like I'm going to get the opportunity to interview 93 year old judo Master Fukuda, who studied directly under Jigoro Kano and whose grandfather was one of the two primary jujutsu masters who taught Kano from which he devised judo. Does anyone have any history questions they might like asked?

You hear a lot nowadays about how the older Japanese martial arts were inadequate, since they didn't stress randori against resisting opponents.

I'd be curious to hear his take on the effectiveness of jujutsu as opposed to the effectiveness of judo.

It's Ms. Fukuda, BTW.
