"Anonymous. Sir. Your weight goes from your heel to the ball of the foot. For want of a better and for this only that is where the body will stop and the foot goes ahead. i did say ahead and not behind the body."
DEAD WRONG!
The weight does not stop in the ball of the foot - it keeps right on going PAST the foot.
If the weight stopped in the ball of the foot, then the movement would be in stops and starsts. Anybody can see that this is not the character of the swing dances - they have continued smooth movement!
