Great Questions !

I love quizes...

The impact point plane line is a chord of the clubhead orbit on a line parallel to the ground. The LOC at impact point is an onplane tangent of the clubhead orbit. The angle of approach travels through the sweetspot impact point to low point. These lines are all on the face of an inclined plane and all intersect at the point that the sweetspot travels through the ball which means it maintains its vertical relationship to the actual impact point via clubface position but centered horizontally viewed directly on from behind.

The line of compression is seperate from the positioning of the clubface for initial ball direction. The ball after being deformed will 'kick' off the clubface and is thus diverted from its tangential path. The line of compression is always going to tangential at impact point but the clubface motion via hinge action will manipulate the line of compression until it kicks off the clubface.

Horizontal hinging for a straightaway flight will sustain and carry the tangential line with the closing of the clubface through impact so that at seperation the LOC is in a vertical plane (which the line of flight will be in) which is parallel with the impact point plane line. For Vertical Hinge action, the compression is lost and the ball does not deform on the face and thus at seperation the LOC is still tangential. Angled - inbetween....

The curvature of the ball is when the clubface is open or closed relative to the vertical plane of the sustained line of compression at seperation parallel to the chord(plane line) relative to the ground. The ball needs to be deformed in order to kick off the clubface to spin the ball on a different plane other than the vertical plane of the initial flight via clubface position at seperation inorder to use the venturi effect to create curvature.

The thrust and the LOC are both onplane and intersect the plane lines.

I've typed this after a long night shift so sorry I've if not been clearer.... I'll reread when wake up and make sure its to the best of my knowledge accurate

This is what I was after! Thanks! I think you are "on to it." I wonder if we could accomplish this with a visual aid? Even if it's just a drawing scanned in? Doesn't have to be one of those fancy high-tech jobs that you are so great at. I will work something up on my end too . . . maybe we can compare?

What do you think?

Again thanks for the help!
