Recently we had a couple of guests at our dojo whocame to visit from Austin TX. (I think that is where Birdsong Sensei is currently living)
One of his students came with him and was doing these "soft" breakfalls as well.
All I can say is WOW!!!
Most impressive. I am just getting into hi-falls now-a-days so I was boggled with it.
Gotta learn this.
