Most good players like to walk over and look down the line of the shot, when it's a strange angle, wether they actually use the contact point or not.
This is only a problem when you look at whatever system you are shilling or using as an infallible, complete package with everything you need to pocket all balls in the center, from just two points of reference (the balls).
Here we go again out of the clear blue sky. More BASHING of a particular aiming system called CTE!!
All the stuff one has learned throughout the years blend into a whole, and for many, myself included, it's tough to tell anyone what we actually key on. For certain shots, I visualize hitting a specific part of the pocket, and it helps me be more consistent. I've never taught anyone this, because I belive it may be specific to me. For all I know, I don't even "aim" my shots anymore.
Who cares what you do or don't do? There's a member of the MC team from the USA that aims and does it with the system you came in here to BASH. He's also a Certified Instructor of the aiming system.
There was another thread in the main forum with a lot of great posts praising Landon Shuffett as a player/super human being and hoping he would play more often. He also uses the system you know absolutely nothing about and continue to knock and he's also a certified CTE instructor. Would you like to play him for some of your own money to see how fast he could bust you like he did to Earl? It would be laughable!

I just focus on where I want my object ball to hit the pocket and the whole thing takes care of itself, mostly. I for the shots that I don't find automatic, I still don't really imagine a "ghost ball" anymore, just look at the line and put the cueball there. You can't teach that to anyone else.
If I were to to teach a brand new beginner this game from scratch, I believe I'd start at the ghost ball (for tangent line knowledge) and graduate to contact points for more precise aiming. Those are imo the most natural and instructive ways to teach. Together they give you both the shot line and the cueball line and are thus the most important puzzle pieces or building blocks to build up a library of shot pictures, or "whole shots".
