More work for Daryl: "Air , your friend mentions right forearm torque . Ask him if the left forearm can torque while the right doesn't ( passively or actively ). And does this assume a 10-2-D grip if the answer is yes"

I only meant that the right forearm can produce a force during a Flip Release and it's not uncommon.

The #3 Accumulator and Pressure Point will Roll the Left Arm while simultaneously keeping the Left Shoulder at the Center. Roll power of the Right Elbow. This is "Hinge Action". Any attempt to square the Clubface by applying Left arm rotational force will cause a Swiveled Impact. This not only results in compression leakage but alignment issues as well. This is the hard way to play Golf.

The guy that you're talking to is a #2PP swinger. He's having a difficult time understanding how the Left Arm Rotates. I know this because he's asking about the 10-2-D Grip. The 10-2-D doesn't need much Left Arm Rotation and is often adopted by players who don't understand how the Pivot and Right Forearm Rotates the Left Arm. If he wants to use a Standard 10-2-B Grip he needs the Right Forearm Angle of Approach and #3 Accumulator Roll. Tell him that at Impact, His Right Forearm, although its pointed downward, must also almost be Pointing at the Target (On-plane, which is almost parallel to the Base line of the Plane). This needs a Pivot with a great amount of Rotation.. Like Greg McHatton likes to say, "it's not how fast, but how far".
