Folks my last comment here........
In doing this art when centers are connected then one of the two parties involved will be in a destabilized or out of balance condition on their way to a fall, a pin, or something like that. If both parties are stable in their movement then ii is dance. When one the parties destabilizes themselves by double weighting to their attacking side or places their center outside of their base by choice or as a purposeful part of their attack they are giving themselves away. Up tempo dance.
just go straight
