And you also visualize with CTE, both utilize visualization techniques. I'm not in favor of ghost ball, except for teaching the concept of where to hit a ball to a beginner. You must execute the shot and learn from the results. This is how you play pool and get in line with any aiming system. CTE limits variables and gives a systematic way to practice pool.
You can also align your stance to CBC to an edge or center of the OB and have good results. This is a method @CJ Wiley
has made some videos of recently. Getting good at pool is all about seeing correctly and estimating what will happen. When we are in dead stroke, our mind/body is just conforming to how the balls behave naturally.
