Remember one more thing. I can't emphasize enough how important progressive practice is. It will be hard for a C player to visualize clear success on a very tough shot on the first day of doing this but by starting with a manageable shot and proving that this works then reaching to be able to clearly picture success with longer shots and tougher cuts you will soon get there. Just keep up the repetitions and don't give up.
Get a clear picture in your head and the feeling in your body then shoot.
This is pretty much the standard advice that most beginners get. Start with easier shots and work up to harder shots.
I agree that all things begin in the mind. Which is why I don't agree that the subconscious is responsible for success in pool. I think playing great pool is a conscious effort and occasionally we can slip into the zone where all the choices are clear, the paths are clear, the stroke is effortless and we are comfortable.
Where I have a problem with progressive practice combined with the Ghost Ball method, personally, is that it requires a ton of memorization and visualization. And as the shots get tougher they get progressively more stressful when they are faced under pressure.
I have spent countless hours practicing this way. Thousands of them. Visualizing the shot every which way possible. I honestly believed that there was no better way to aim than ghost ball as taught by Robert Byrne and endless practice. But in the interim after learning Hal's methods a whole other world opened up. Which brings me to the point, what good is climbing the ladder of success if your ladder is leaning against the wrong wall?
If you spend countless hours doing progressive shot drills only to find yourself still inconsistent then what's the point of all that. What if you could learn a way to aim that required you to memorize a fairly small set of visuals and it was a 100% surety that any shot you face, no matter how "tough" it appears, was covered by one of those visuals?
Imagine for a moment that you come up on a shot that you have never faced before in the middle of a critical game? Would you want to be stranded with a method that requires approximation and a ton of practice to get comfortable with the shot or would you rather be able to look at it and see the right formula for aiming it immediately?
I don't care what shot you present me with. If it can be made directly into the pocket then I can make it within three tries even if I have never seen it before and mostly within two tries. And I am a lousy player who is too lazy to actually master ProOne.
In game situations, some of them for real good money, I have relied on CTE to pull me through on clutch shots. I have gotten actual live applause from railbirds for coming with shots that most people think are impossible or crazy to take. But this is the difference to using GB, for me, with GB there is that uncertainty, that lack of practice hitting THAT shot hundreds of times that translates into nervousness and a lack of confidence that messes with the execution. So even IF I had managed to visualize the shot properly using GB I still could dog it out of fear that I hadn't visualized it properly.
But with CTE I don't have any of that. None of it. You simply see and shoot right out of the gate. See it, decide on the aim combination, go into the stance and shoot. It flows with almost automatic precision.
So now, when I do shot drills it's not to learn how to visualize the shot. Instead it's to train my self to see the right lines on the actual balls in front of me and to be sure that the ones I pick are the right ones for that shot. Once I have that down then I never have any trouble with that shot or any similar shot again because the same visuals cover a range of similar shots.
Your last comment about not expecting a C-player to get the right visualizations out of the gate is another thing that has seared Hal's aiming methods into my brain as the better way, for me, to aim. When I first learned Hal's methods, not CTE, I went to a tournament held at a local bar and showed the owner and her boyfriend this method. The owner was an APA 3 and the boyfriend was a low APA 5.
I, being still skeptical, wanted to test this out on them and see if it made any difference. Melanie, the owner, started immediately making shots that were WAY over her skill level. John was also making better shots. Anyway they were both impressed. So to me, it's like this, if I can give a C-player a method to use that works regardless of their ability to imagine and works without needed hundreds of shots for every shot they need to learn, then that's a better method. Then they can work on their execution more and develop the type of smooth and solid stroke they will need to go with being lined up dead perfect.
