Thanks for sharing. The use of opposing forces is something I do not focus on, but indirectly have students think of their 'other' hand when moving. Many tend to focus on the hand that is attacked...
As a next step, try thinking of a spiral stretching from the hand being grabbed (for convenience, let's say it's the left), across the shoulders, and around to the other (right) hand. To draw the person toward the left side, try extending the spiral from the right side.
