Sorry for multiple post. If u are dealing with weapons and controlling your opponent on the ground, I think transitioning between levels, yeah good fundamentals in aikido drills and exercises. That said, it ain't fighting and there is so much more that must be considered...but foundational skills...yes much embodied in good waza.
Thanks, the reason I ask was a prison guard I trained with some years ago, he said he used suwari waza
techniques regularly when he had to subdue violent inmates and the fight went to the ground.
