I'm not sure about the BALL FLIGHT LAWS THEORY either.
If the SHAFT and SWEET SPOT are on PLANE and the(SLIGHTLY OPEN) CLUBFACE contacts the INSIDE QUADRANT of the ball at just the right place in relation to LOW POINT, with HORIZONTAL HINGING and proper RHYTHM... THE BALL SHOULD GO FAIRLY STRAIGHT. CHANGES OR ADJUSTMENTS IN THESE FACTORS CAUSE CURVES.
Once all this is in your COMPUTER... you should be able to produce your shots with a very simple cue.
