The thing that this technique taught me was that English is WAY over rated...yes, spinning shots in and using English (side spin) to move the cue ball after contact is critical...but not nearly as often as we tend to think. Using this technique, using speed, draw and follow to control the cue ball works 95% of the time--no kidding. I can put the cue ball pretty much wherever I need to without relying on side spin. Once you get used to using this, you'll wonder why you ever thought you needed to do anything else. Now, when I spin a shot in, I'm amazed at how "out of control" that feels now. You start to see that relying on side spin instead of the natural angles is so much less reliable.
Another point that was getting debated to death was over the spin that TOI puts on the cue ball...if you're doing it right, that small amount of spin is killed on collision with the object ball (especially on thicker cuts) and the cue ball "floats" with no real spin after that. Then, even as the object ball smacks into the center of the pocket the cue ball just creeps into the zone you where visualizing when you pulled the trigger.
As for one pocket or 14.1, this technique doubled my average runs...not that I was a real pattern player to begin with (although 8 ball is my game). I halved my innings average in 8 ball, too.
Well choosen words, hats off sir
