Spidey:
My only point is the edge at the equator is excellent perception-wise for nearly every shot in pool...break included.
OK, that makes sense to me even if I don't understand all the details of your technique. I guess the message to players who might want to try this is "there's more to it than the simple description given here".
Not saying it's the only way nor am I saying it's the best way
It's the best way for you, and maybe for others. I'm just clarifying if the way you describe it is complete or not.
