Neither is GB. I use BHE and judicious speed no issues.I don't understand how anyone can aim at the geometric contact point. It's not reality. The CB squirts and swerves and throws the OB.
There's a whole forum for aiming topics. Maybe this thread will get moved there, but in the meantime....
Suppose you can keep the contact point in mind, say it happens to be a feature on the object ball. What do you then do with that point once you get over to shoot the cue ball?
You learn to visualize this:
Diagram is lopsided but you get it. Once it sinks in, you can just visualize this:
This depicts a different shot but who's counting. Three dots in a tilted line across the face of the ball; the highest one is the OB contact. You can connect the dots while standing to determine the stick line. I find that's usually all you need; some kind of line.
Portrait artists have to imagine a whole universe by comparison.
