Player needs to learn these things.......
Every shaft plays different. Another thing aiming systems can't account for is speed. Different speeds equal different aims, no way around it. Sorry.
Every player needs to learn how their shaft is going to react when they hit a ball hard, soft, right or left English, draw or follow.
A player should already be factoring what they are going to do in the preshot and be incorporating that into their aim.
Example: You have a maple shaft and you are putting allot of right English and shooting hard the full length of the table. You better aim to the right of the object ball to allow for the deflection. That shaft is going to shove that cue ball allot to the left before it even gets there.
Asking an aiming system to do this figuring for you is rediculous. A player needs to learn where they are aiming and hit what they are aiming with their adjustments included..
Or hitting a golf shot with the wind blowing to the left at 15 miles an hour. You better aim the shot a bunch to the right but you still need to aim the shot correctly. You need a definite to aim at.
You can use shadows, lights reflections on the object ball or other things as a reference but a player needs how to adjust for all the other variables that there are when figuring out how to pocket the ball.
Like a sniper trying to hit a target with the wind blowing 10 miles an hour from left to right. He better adjust his aim to the wind or he'll never come close to the target at 300 yards.
The good thing is that there are qualified teachers all over the place that can teach players these things.
There are 100's or maybe even 1000's of great BCA instructors all over the country. Thanks to people like Randy G and Scott L. These guys will hook you up with someone local if they can't get there themselves.
Most of the time a player right in your poolhall that plays at a higher level can help other players understand these things. Pick their brain. It's not rocket science but you do need to understand it or you can't explain it.
I hope this clears this up a little. Just trying to help.....
