basically every pool players relies on a "system".
Its how he views the table, how he approaches the shot, the warm up swings etc... all is part of the players system to get comfortable.
The problem which we have in this thread is, once again, that all is about an aiming system, even though the TO sais it can help your overall game.
What most players (new unexpierenced players as well as seasoned players) struggle with is defining their own approach of the game, their "personal system". they forget to check the angles, the easiest way to get to the next ball, they approach shots differently at different speeds etc... which makes them, in a long term, inconsistent, especially under pressure situations.
Now, if the TO wants to sell his product here, i dont see a problem. Some players maybe need a "guide" how to approach every shot in the same way. I remember a german (or was he dutch? dont know

) coach who had different "checkpoints" before going down to shoot, pretty much like a pilot before he starts the engines. The goals was to teach the student a routine he could rely on, because its the routine that gives us comfort, reduces stress and makes it possible for us to rely on our skillset.
The point is, and thats what most "nay sayers" (me included) try to point out (some through discussion, some with offending people), is that
a) not every "system" works for everyone
b) proper fundamentals are WAY more important cause you can plan, aim and develop every aspect of your game as much as you want, if you cant deliver propperly you gonna miss
which leads me to the final point :embarrassed2: a system is not a garanty to play good, its "only" there to put you into a comfort zone that your TECHNICAL skills to shoot one given ball at a given time can be used to 100%
