OK, what kind of speed you talking about?
The visual alignment is for center pocket for a center ball hit, so yes on some strokes i adjust.
Yes i look at edges. You can focus on OB or CB for your last stroke. IMO it is a matter of what you are comfortable with.
Haven't had a personal lesson in a while but have been given all the updates so yes i believe i am using it as Stan teaches it.
He teaches many things in his private lessons, hence the word private.
So produce a video, i haven't found one. And don't forget to point out the many uses of his foot positions.
