For Colin and JB:
Colin - fantastic job on your fixed bridge video! I love it! This is exactly the kind of thing skeptics of CTE would like to see more of, but I understand that not everything is subject to this kind of testing.
When you say that the stroke isn't that important I now see where you are coming from. Correct me if I'm wrong, but you are really saying that the stroke isn't important IF you get your bridge to the natural pivot point of the cue -- that being the point on the cue that balances out squirt with the offset aim. In other words, when I apply right english with BHE, I am pointing the cue to the right of the correct aim point which will send the cue ball to the right, but the off center hit will squirt the cue ball to the left. If you are at the pivot point of the cue, these exactly offset and the cue ball goes to the correct aim point.
Of course the above does not eliminate the necessity that you be able to hit the cue ball in a precise location. There is more to playing the game than pocketing a ball. You need to get position, too, and if you can't stroke the cue with precision then you will have trouble with that part of the game.
I had a phone consultation with Hal years ago, too. He was generous with his time and was a real interesting character. I tried to apply what he said, but honestly I didn't get that far with it. I didn't understand how it could work in all situations and I was pocketing balls pretty well anyway, so I discarded it. Here's the crux of the problem for me: I set up a shot in the side pocket, not too far away. I set up one of the center to edge positions and pocketed the ball. I set up the shot again but moved the balls and inch to the right. I hit it again and the ball missed the pocket wide. It just seemed there was a problem with the geometry. I have to assume that more modern CTE systems are able to reduce this kind of error, but don't you eventually get to a point where you are just aiming by feel anyway?
Here's a shot I set up when I got home. I picked up the cue and shot it right in center pocket. What is CTE going to do for me. Or, is CTE marketed toward people who are having problems pocketing balls?
It seems to me a lot of the debate and anger would disappear if one question could be agreed upon: If you use CTE, do you still need to use your intuition/experience/feel to pocket balls in between the CTE aim points, or does CTE tell you exactly where to aim on every shot with no further fiddling needed? If so, how can this be done when there are discrete aim points with CTE? I do not buy the explanation that it has something to do with the roundness of the balls, because nobody was ever able to demonstrate how that geometry worked on a piece of paper. I don't think anybody has a problem with the use of CTE as a means to improve pocketing ability. I think people have a problem when it is sold as the answer to everything when it doesn't seem to be clear exactly how it works beyond the basic angles you can predict from center to edge points.
