When performing the "x-block" movement, be it high or low, which hand goes on top and why? I use this position for various purposes including transitions, chokes and locks. Thinking it through all of the kata that I know that have this movement have the hand of the rear leg on top. I'm thinking Pinan/Heian Godan and Chinto/Gankaku. Yet in Taekwondo it was strictly the hand of the lead leg.
My students asked this this past week and correctly guessed my response: don't worry about it! In the time it takes for you to figure out which hand should on top you're already taking damage. Yet for precision of performance of kata / forms there is definately a "correct way."
What are your thoughts?
