I've been in a slump for 4 days, so don't even read this post!
My initial visual center alignment is always center to (rough) ghost ball (CTGB?)
I look at the pocket, visualize a line straight through the center of the OB. I then visualize this line intersecting the equator on the visible side of the OB. It is important to clearly understand that the equator line of the OB is perceived as an ellipse from any practical eye elevation. Depending on the lighting conditions, you can even see both hemispheres roughly divided by the reflection of the rails. This intersection is the physical contact point. Our eyes and brain can see this very precisely - at least at the precision required to pocket a ball.
The rest is where I believe the difficulties multiply...
People dissing ghost ball will say that you're aiming at something that isn't there. That's true, but that's not the way we should be thinking about the ghost ball. PJ says he shoots at a learnt distance (1 1/8") from the OB. That's accurate, but I believe our brain has a hard time seeing that. I think ghost ball contact patch suffers from this also.
I truly believe our brain sees areas and volumes better. Once I clearly see the contact point, I ask my brain and body to make the cue ball (a volume which is, as luck would have it, the same as the OB) go touch the OB at the contact point. With this in mind (and other considerations such as which position/spin/speed I need), it's time to assume shooting stance all the while looking at this picture with eyes focused on the impending collision of the two spheres, but with the brain aware of the pathes of CB-to-OB and OB-to-pocket.
One of the smartest things I read about aiming is on Dr Dave's website: "Good shooters use all visual information available to them to help see the required angle of the shot and the necessary line of aim."
I started looking into the various aiming systems that are around, thinking it would make my game more consistent. I came to the personal conclusion that my aiming was fine, but I didn't care as much for making all balls as I would like to believe. Sometimes I'll shoot some ball instead of another, not because it's the right sequence, but because the shot appeals to me for other reason, like: let me try that combo, I like those reverse english shots to the side pocket, etc. I decided not to worry too much about behind super-humanly consistent, because it seems, at this point in my life, it's not that important to me. If I catch myself thinking: "I which I were better", the only answer I could give myself would be: "Really? Then do what you need to do, and
mean it!"
I hope you haven't read any of this, as I'm having a hard time beating the 6-ball Ghost!

But if you did, can you relate to any of this?
Pool: a game I love to hate... Or is it the opposite?
