Whoa, easy with this one.
I would never ask my teacher, Donovan Waite shihan, to show me something at "full-power" or "at speed".
That is just asking for all sorts of hurt, yikes.
Be careful what you wish for, indeed.
... Good luck with this one.
wow... I was at a course that Donovan Waites took, and got to feel his kotegaeishi. amazing experience. I wouldn't like to be on his receiving end for 'full power'
