I think the Aiming Point Concept is a problem because if I ask 5 who "understand" TGM I will get 9 explanations. I hold with those who place it in the area of "impact Fix" hand location. Not near the plane line but close to the left toes. (visual). This helps (me) keep my hands down. I agree that if the aiming point is placed on the plane line one may tend to lift the hands.
