Right Arm Flying Wedge
The Right Arm and the Clubshaft are positioned on the plane of the Right Wrist Bend - ALWAYS at Right Angles to the Left Arm Plane.

In what way is this an important aspect to keep in mind?

I think you mean "AWAYS at Right Angles to the Plane of the Left Wrist Cock , the Left Arm Flying Wedge." Again the "always" troubles me. For instance Homer by his own definition described the 10-2-D grip as having the left wrist cocking along the same line as the right wrist bending. So that being the case wouldnt the Left Arm Flying Wedge and the Right Forearm Flying Wedge , for this grip type , be similarly aligned , not at 90 degrees to each other? I think Homer would agree with this.

Im not saying Homer was wrong for the record , just a comment about his writing style. The statement in question stands , assuming a 10-2-B grip, which he always assumed. But... does the reader get this?
