Ok, here goes. I use a modified point-of-light aiming system for many of my shots. I modify it depending on the way I'll shoot the cue ball, whether it's with draw, stun, rolling, follow, and with or without english.
Here's the way I've figured out how to make this thing work for me, and depending on the cue and cue ball/object ball combination, it all changes. Anyways...
The first thing I'll do when warming up is set up a moderate cut shot, something between 30 and 45 degrees, with the object ball say 2 diamonds from a corner pocket, and the cue ball about a diamond away. I find the specific point in the pocket I want the cue ball to go and imagine a laser light from that specific point straight from that point coming back through the object ball dead center, and see that imaginary laser point on the object ball. Then I'll put the tip of my cue on the cloth approximately 1/2 inch to 3/4 of an inch away, hold it there, angle my cue over to where the cue ball is, and dead center the cue shaft over the cue ball, use that line for my initial angling and shoot a dead center, medium stroke shot, rolling the cue ball to the object ball. It may go in, it may not. What I'm doing is getting a feel for the angle necessary with this shot to pot the object ball exactly to the point I wish it to go. Obviously, if your stroke is not straight this systematic approach won't be consistent. If I don't pot the object ball in the right spot in the pocket, I'll set the exact same shot up again, and make an adjustment to where that point in front of the object ball is, until I get it down perfectly. Once I have that down, I memorize the exact location of the cue tip on the cloth to make that shot sing. Next, I'll set up the exact same shot, but this time shoot the shot with a force follow. Try this and you'll see that the object ball will most likely throw to the inside and you'll miss the shot. How do you fix this? Well, just make that aiming point on the cloth before the object ball a bit closer to the object ball. In essence you will be hitting the object ball a bit fuller, to counteract the throw. Once it pots perfectly, memorize the exact location of that point your aiming at. Then do the same thing with the shot but with draw. You'll find the aiming point will again vary, because of throw, but this time, your adjustment will differ again.
All this is just with a center ball hit!
Once you get this down, and adjust to the balls and the table and so on, this method is pretty accurate. If you find you need to shoot with a powerful force follow, or a scorching draw shot, you'll know what to do. Add english to it, and get ready for more adjustments.
How does this work, at least for me? VERY well, and if my alignment is on, and the shot is grooved, that object ball is going down.
About a week ago, I tested this aiming and stroking system out, on a 9 foot table, shooting about a 30 degree cut shot as described above, but I moved the object ball further away from the corner pocket. It was probably about 3 1/2 diamonds or so away, and the cue ball was probably about 2 diamonds away from the object ball. I say "probably" because I varied the shot in different ways for 6 shots.
I did my aiming as described, set up for a powerful force follow, grooved my stroke, turned my head away and didn't look at the shot, powered the cue ball and heard the object ball smack dead into the pocket. I moved the balls around a bit, aimed and set up for a powerful draw shot, grooved my stroke, looked away, let 'er rip, and down that object ball went. Did it 4 more times, each one a different shot, and each object ball went down.
The slight variations in angle depending on strength of stroke and where on the vertical axis the tip hits are extremely important, especially if the object ball is further away.
This method takes into account the relative condition of the balls: clean, dirty, waxed, polished, and adjusts for them. It also takes into account whether they are red circle, blue circle, measles, centennials, aramiths, WHATEVER. It is very important to get a feel for the actual conditions on the table, and this outcome based approach has helped my game a lot.
Also, if you need to shoot with the cue jacked up, this will also change the angle a bit, and you'll need to adjust. With time, you'll make the adjustments naturally, almost without thinking about them.
Will it work for you? Maybe, maybe not.
Why not give it a try?
Cheers!
