It does present some risk - as there is a point of potential unbalance for tori - as i discovered when a 110kg close protection worker got me to the floor on one occasion but generally it works well.
Yup; there is a small moment of weakness and possibility to be unbalanced at the turning point of redirection. The transition also has to be smooth; no jitters.
I forgot all about this and gotta bring this back to try out in the dojo later this month.
Am surprised this is still being thought about and discussed.
