Hi, i am planning to write an article about differnces in teaching different ways of breaking a fall. Idea can to me after getting to know a little Han Moo Do which is a Korean style. They taught usiro ukemi with a littel hand push to increase a roll. In other styles it not allowed in fear of breaking a wrist. I think there might be other differnces too.
So help is needed to find differnt instruction on how an ukemi is developed and the application.
Here is a youtube playlist of ukemi http://www.youtube.com/playlist?list=PL804501FC20C2643D
