CJ:
I agree with the bolded parts, but with one proviso -- not all of us aim "center to edge." As you know, there's a "system" in snooker called Back-of-Ball aiming, where you treat the balls as if they are flat discs.
Although I am a student of this game and open to all knowledge -- including studying Stan's DVD (just today, in fact, I popped it in and reviewed) -- I can confidently tell you that Back-of-Ball aiming in no way/shape/fashion resembles or uses the same aim lines as CTE or Pro/1.
For example, in back-of-ball aiming, you do *NOT* look at "center to edge." Rather, it's a fractional "eclipsing" system, where the edge of the cue ball "connects" or "cuts through" a fraction of the object ball, and vise-versa with the object ball -- that object ball's edge "connects" or "cuts through" a fraction of the cue ball. The beauty about this system is that the visuals, once the foundation is built, is AUTOMATIC -- you see them, you get down on them, and you shoot directly *at* them. No pivoting.
Back-of-Ball aiming does require "homework" on the part of the student -- that he/she commit to memory some common ball-to-ball angle relationships. I.e.: 1/4, 1/3, 1/2, 2/3, 3/4, 7/8, and "thin" cuts. This is necessary to have a foundation to build on, as the subconscious mind "knows" the adjustments to these foundational ball-to-ball relationships to "finish" the shot.
I think what you're trying to say, CJ, is that in order to play at the top levels, you *have* to be playing from the subconscious. You *CANNOT* have the conscious mind engaged where you're saying things like "this is a half-ball hit, but because of throw, I have to cut just a hair more." Or, "I have my two aim lines -- CTEL and OBA -- and I'm going to come down and Pro/1-pivot into the shot." Thinking like this is a recipe for disaster -- i.e. programming yourself for a MISS.
I think *all of you* -- naysayers and yeahsayers -- are thinking WRONG. That word -- thinking [about aiming] -- is what's keeping this Hatfield and McCoys feud going. And that's all that "thinking" is good for.

I don't believe everyone has to use the center, the edge or the contact points as a rule....I do believe they must connect the cue ball to the object ball in some relative manner.....quarters, eighths, center to edge, edge to center, quarter to a quarter etc, or some kind of eclipse system which is still a fraction at a fraction..... I just prefer to aim ABOVE the shot and then use the center to aim once I"m down....because using the center gives me the most feel and at that point I think you can aim whatever part of the cue ball you want.......when lining up with my body I use the edge of the cue ball.....the same side as the direction I'm cutting the ball...thus I use 2 lines.....one for my body and one for my eyes.....and they both connect to the object ball in a place to create the desired "cut" or angle.
