It's funny that you should say it like that. Back in the mid 80's, when I first started playing, the owner of the local pool hall, fantastic one hole player, was teaching me to use english on my shots to obtain position. He didn't go into a long serenade about squirt, swerve etc... When I got down and shot the ball with english, and missed of course, the only thing he said to me was shoot it until you can make it. I think that was probably one of the best pieces of advice I ever had.
I think cluttering up your mind with all that crap about how much is it going to squirt, how much it could throw depending on the thickness, breaking down the angle of the shot etc... etc... puts your mind totally in a funk. It's like you say in your post, hit the cueball into the point on the object ball that will send it to the pocket. It couldn't be simpler than that. If you miss it, keep doing it until you don't.

That is some extremely good advice, Mully. I teach my students about squirt and throw and all that "crap", but only to let them know that those things do exist and that aim compensations must be made when those things are present. Also, knowing how that crap works lets the students know whether to compensate left, or compensate right. After that, I tell them to PRACTICE! I cannot, and will not, try to give them a bunch of formulas and systems to make the balls for them. I feel the same way about all other aiming systems, banking systems, and kicking systems. I just do not believe there are any "systems" that can allow for variables like cloth speed, cushion rebound, ball speed, friction factors, eye sight, etc. and have the player be any better than if they would just PRACTICE more. I tell my students that (in my opinion) systems should only be used to get them in the "ball park" of any type shot they are having difficulty with. And once they have a feel for how to aim a particular type of shot, then scrap the system and shoot by feel.
