Good drills and this time I get to say I have worked on similar things.
Taking it a step farther from the push, we have put people in the HIGH GEAR had them close their eyes and then you hit them in the face instead of a push and you keep going at them so they have no recovery time. Maintaining you centre and balance is a good thing to know how to do in these cases. And yeah you will be knocked backwards until you can overcome being struck and take control. However, it is just not as graceful when folk keep hitting you.
And I know these are just drills so the question I have may not be relevant or appropriate so take it for what it is worth.
After the first flinch you hands are so close to the aggressor’s head, and he is still moving forward, it seems to me to take the time to step all the way to the side and perform a full intercepting Wauke is just not as efficient as dropping your hands down slightly to meet the oncoming aggressor (ala Seisan Kata). In fact, if you speed the drill up, it seems to be the efficient response.
Or does the drill go there in the advanced form you didn’t have the folk to demo?
By the way love the “manly men” shots you take – lots of laughs -- hope we can all share a good laugh.
