Working with a student we found another great awareness using the Tour Striker Educator. Set the device behind your trail forearm at address in the "2nd notch," or at the 45* angle. You'll realize that a club resisting the change of direction (lag) will reposition the Educator arm toward the top side of your trail arm. You are able to feel torque and forces you need to do and it will help you deliver the correct sequence to the ball at impact.
