"The most important thing to STRAIGHT ball-flight is a ZERO PATH.
To do that you have to swing left enough for the resultant path to be ZERO.
To do that you need either some a) EARLY CARRY or b) mid-downswing tumble.
To do that you have to be able to have enough width so you don't back out of A or B.
Then you need a ZERO FACE."
I think that's BS! One doesn't need any "mid-downswing tumble" or any "carry" to hit the ball straight. If one needs to "swing left" to zero-out the path (which is required when one generates a negative clubhead attack angle), then one can simply move the baseline of the inclined plane leftwards by the required amount. However, one doesn't have to change one's swing biomechanics in order to trace the SPL of the "new" leftwards-shifted baseline of the inclined plane.
This golfer can hit the ball straight if he traces the SPL of the ball-target line and generates the clubhead arc in blue that is square to the target at impact - if he has a level strike at impact.
When he hits down on the ball, he simply has to move his inclined plane leftwards by the required amount.
Image 1 applies to a level strike, and image 2 applies to a downward strike (negative clubhead attack angle)
Note that his baseline is shifted leftwards (red line) in image 2 and his clubhead arc is symmetrical to the red line, and square to that redline at impact - if he still traces the SPL of the baseline of the inclined plane. There is no change in swing biomechanics required to zero-out the clubhead path when generating a negative clubhead attack angle - there is only a need to shift the direction of the baseline of the inclined plane.
