DR jujutsu & aikijujutsu are not different names for the same thing. They are in fact...different. I think the disconnect here is that what some aikidoka think is aiki is really just ju. Don't take my word for it but research what DR aiki is/looks like and then compare it to aikido's aiki.
You may discover what you are calling aiki isn't what DR calls aiki & is in fact just another extrapolation of the ju principle. Just my 2 cents.
I am not familiar with differences between the syllabi, but my assumption is that the techniques on the jujutsu scroll can be performed with aiki, and that if I were to watch Konda Sensei perform them at an embu, he would be performing them with aiki.
Do I have that wrong?
