Dawgie said:When I first started playing seriously ( one year ago this past June) I kept hitting the c/b slightly off center to the right. I learned this through the center hit excerise that requires you to hit the c/b to the rail and have it come back to hit your tip. NO SPIN ALLOWED. I moved my center hit point over to the left a little and the c/b started to come back straight to my cue tip. Now when I hit the c/b it always looks like it is a little to the left. I think the reson for me hitting a little off center in the beginning was due to shadows around the c/b. the lighting is good but you will always see a bit of shadow to one side of the ball of the other which gives you an optical illusion as to where the center actually is.
I think this is a great way to learn to strike the center of the cue ball horizontally (meaning you learn not to use side spin). The only difference I suggest, is the change I made for a young woman who amazingly enough struck every shot with extreme left english, and argued me down that she hit the center of the cue ball. Put a striped object ball on the foot spot and aim at the center diamond on the head rail (the short rail where you break). I added a piece of chalk on the diamond for her to aim at. The ball on the foot spot should have the number facing you in the center of the ball. You can check the other side of the cue ball to make sure the other number is the same height, or use the second object ball touch method suggested by Snorks and credited to poolsponge (I really like this method, kudos to the sponge.).
This gives you an aim point. Once you get used to where the center aim point on the ball is, you can watch the stripes immediately after the strike for your vertical center feedback. If you hit it correctly, the stripe should not move for a short period immediately after the hit. If the top of the stripe moves toward you immediately after the hit, you struck too low, if it moves away from you, you hit too high.
Then watch the rail for sidespin feed back. If it strikes the rail and moves to the left, then you know you hit too far to the left of center and the same for right of center.
Sorry so long.
