Let me ask you a question. Do you really think that it's easier to learn to swing 1 degree upright for your Wedges and 2 degrees flatter for your 5 iron or Play your wedges 4.45398" back and your 5 iron 2.87456" back? How would you handle a downhill or side hill lie? Have you ever used Trackman while in a Bunker?

First and foremost is Angle of Approach and Angle of Attack. Re-aligning the Hoola-hoop is not Angle of Approach. Certainly there's a "correlation" and Trackman capitalizes on this. But it's very misleading.

On the Circle, Angle of Approach and Angle of Attack are ALWAYS zero. Only in a relationship between the Neutral Hookface design of the Club, on-Plane and seeking the Target Line intersection, can we have an Angle of Approach and Angle of Attack. So, all AOA and AOA need to reference Low-Point. Trackman doesn't know where Low-Point is located and Trackman doesn't use the Face geometry of the Club. First, because Low-Point isn't a Location and second because Trackman doesn't capture or measure the Clubface geometry.

SO, Trackman teachers rely on a flawed correlation which cannot possibly correct a swing flaw that has nothing to do with it anyway. You'll end up with a different swing for every club in the bag. Instead of learning one compensation, you end up learning many. Much more effort, frustration and learning than doing it right to begin with. Swinging on a steeper Plane doesn't turn a Hacker into a Golfer.

If a Hacker learns the Right Forearm Angle of Approach, then he/she will flush a 2 iron as easily as his Pitching Wedge and, he can use any Plane Angle he wants.
