Good shooting. But an aiming system doesn't help you with the cueball on the rail. Your excellent results in that video are not only a testament to your aim, but also to your stroke and fundamentals.
Hey jsp! First of all thanks to you for your "good shooting".
Sure you are right.
The ability to play good pool needs more than just aiming!
You have to have a good alignment, a solid straight stroke (if not work on it

) being able to handle throw, you need to have good fundamentals, theoretical knowledge about the game, mental strength...and a lot more. Let's say it is pretty much like a puzzle. You need every single little piece to have the picture completed.
Imagine the puzzle to consist out of 50 pieces- but they are not all of the same size. Some of them are bigger than others. I think the pieces on which you find the words "precise alignment" , "consistent aiming" and "handling throw" are written on their backsides would be among the bigger ones!
I don’t want to convince anyone who is not interested in CTE/ProOne/90/90 or my system. I can only tell you that I had the other fundamentals apart from CTE/ProOne and my system before. I played around with several other systems before (ghost ball, SAM, Joe Tuckers system, the ultimate system, perfect aim, ferule aiming just to name some. All of them have their good points, but I never shot as good as now! And the miracle is “CONSISTENTLY”! I mean I play pool for 24 years now and have some 100+ runs in straight pool (high score 132) in my pocket- but never felt so sure to make difficult balls now with consistence.
Sure, for easy balls I don’t need any system, but for difficult ones it helps a lot. By the way because of your confidence that rises because you know that you will make this difficult ball 8 times out of ten, using the system, your stroke is a lot smoother and straighter too! You will see-you can ban the word “choking” from your vocabulary.
I still I have to learn a lot about pool. I think you will learn as long as you play (in case you are open to new things...

)

If you want a drill that tests purely a shooter's aim, then a drill should be picked that doesn't require shooting off the rail.
What kind of drill would you suggest?
I think it should consist out of at least 15-20 shots with different angles.
Distance between the balls should be not to close…
Looking forward to your reply!
