I certainly don’t have your pedigree or background, but I still agree. I took aikijitsu as a teenager … and was mauled when I started freestyle wrestling. The locks and restraints, as taught, don’t work on a mauler without an assist and certainly don’t carry weight with a marginally competent grappler. I read Kano’s books and early 20th century Japanese Jiu-Jitsu books. What I found was surprising. The locks were followed with Judo-like throws onto the side of the locked arm to power slam an opponent to the ground. One instructor recommended rabbit punching or kicking a downed opponent. The arm twists were done so as to cause spiral fractures.
