Posing a question for my own curiosity, and maybe it could lead to a technical discussion.... When throwing via Seio Nage, do you throw opponent or uke more "up and over" your shoulder where it is a straighter trajectory to the floor but you are momentarily fully under uke? (I've been told this is the traditional, Kodakan way). Or do you and load uke and then rock your own shoulders in such a way that uke travels more to the side as they are thrown? (If I am throwing over my right shoulder, this would mean looking and pulling toward my left side as I am executing the throw, uke ends up with head in front of my left foot). I was shown this way by another Dan level practitioner. I could see the "up and over" type could create a more devastating impact with the ground, but the slight spiraling nature of throwing to the side seems more graceful and friendlier to my uke, and less of a risk for me if throwing someone much larger than me since I am not loading them on top of me as much. I am likely wording this terribly. I consulted Kano's Kodakan book but its still not clear to me.
