You asked me about my aiming system. Here goes, in spite of my reluctance to post any system here...
I have 6 planes of aim for about 95% of my shots. The 5% outside those 6 are found mostly via the parallel thingy, usually very thin cuts.
Straight on is zero....center of tip is at center of object ball and through the center of the cue ball.
Aim plane #1 The side of the cue tip at the center of ob through the center of cb.
Aim plane #2 is the only one without a specific spot to aim, that is, aimed halfway between the center of the ob and its edge.
Aim plane #3 is the outside edge of the cue at the edge of the ob.
Aim plane #4 is the halfball shot that everyone should know regardless of systems, where the center of the tip is at the edge of the ob.
Aim plane #5 is the inside edge of the tip at the edge of the object ball.
Those will make 95% of shots. Only 5 places of aim!...6 counting the straight on shot.
Learning how to shoot only 6 shots takes much less time than hitting a million balls. It also then really simplifies the playing process so that allows more time and energy to be used for strategy, pattern play, etc., a double win. It also can intimidate an opponent as you easily pot a ball in the middle of the table that requires a so-called back cut, for example. Just determine the aiming number and fire away: plunk!
OK, now take shots at me! Don't use an aiming system, though.
