Shifting planes should not take either ends laser off the plane line. 1-L-18.
I have one of those laser gizmos too and like it as well. Mine actually points a laser out of the #3pp at the sweetspot which I like. Dont know if I should mention the make, but lets say its offered by a guy that used to coach Tiger Woods. Im thinking the genius of its alignment is probably mere happenstance. No offence to Dutch Barmon , I just dont think he had Homers geometry in mind, thats all.
Remember it is really the Sweet Spot plane that travels the Inclined Plane , the shaft and butt end are only handy, close approximates. The #3pp is the lowest point on the grip that attaches to the shaft, making it the top of the Sweespot Plane, the Longitudinal Center of Gravity. Take a plum bob line and attach it to the top of the grip, where it intersects the face is the commonly termed Sweetspot , but the entire line is the LCOG. Now move the top of the plumb bob down to a lower point on the grip, where the #3 pp would be approximately. Notice how the place where the line crosses the clubface has moved!!!!!!! The sweetspot on the face has moved!
Gripping down on a club moves the sweetspot. Lag Pressure is the feeling of the Sweetspot, so direct that pressure at the ball. The shaft rotates around the LCOG, not vice versa. " The Sweetspot is a point without dimension", said Homer. Like a balance point.
So running the shaft down a plane or rail is good for training but not exactly what is going on when swinging. The shaft will be under the plane at impact. Which is why Homer preferred a flash light held at the #3pp for plane tracing exercises.
The high jumpers COG never gets over the bar but his arched body does (and he rotates his feet around it).
