Well, you might be right! I may have miscommunicated, yes, since you have not addressed the physics and logic presented. Read all my points below if you would and let's see if it helps us both.
1. We both know most strokes are taken over a rail, producing a downward angle of attack.
2. Down-angled strokes can jump or micro-jump.
3. Up-angled strokes work like striking the ball on the upstroke with a putter (like a pool stroke in that the backstroke and after, the bottom of the arc, are already completed - then we go past the starting address point to impact the ball). The golf ball starts with immediate or near-immediate topspin and seeks the path (very) well.
4. My point about address is that most players have a cue tip held away from the cue ball and then adjust to hit the point they aim. And many of these players miss that point they aim for, yes? The upward technique, however, is fairly easy to master. I shouldn't have confused the issue by going on this tangent, but whenever backhand cueing techniques are suggested, naysayers talk about missing the all-important cue ball point of impact, as if everyone's regular stroke (which requires backhand movement!) is just a-okay for 100% of shots. If everyone was hitting the cue ball with their regular backhand motion where they aimed . . . however, if you personally want to simplify your game with one or two strokes only, I understand. But one thing I've learned in pool is that there are always new techniques I can learn if I'm open to them.
5. The "answer(s)" for a draw stroke we can discuss next if you wish. But be logical--it will be a first cousin of the issue with the topspin stroke. We both have seen players inadvertently jump the cue ball on draw strokes. For draw or topspin, some players need to adjust grip--speed--aim--and angle of attack. Here we're discussing angle of attack.
6. I agree where I can with people. I agree with Scott that non-pendulum strokes fall into this technique. However, we both know that most players don't use pure pendulums, particularly on the second half of the motion past the checkoff point (the cue ball strike). My point? If you're an elbow dropper, loop stroker, piston stroker or J-stroker, you can hit the ball with an upward strike. You can also do it with a pendulum stroke if you want to learn how. I advocate stroking through the cue ball on a regular center ball hit to bring the tip to or near the cloth, sure, but there are an arsenal of strokes available to us if we think outside the box.
7. Do as I do. I ask clarifying questions about things that are new to me rather than insist "that can't work" or at least I don't dump on a new idea right away.
Your comments show you aren't attempting to track with me. Let's change that. I've showed dozens of players this technique in person and also told thousands of people online. It's a subtle movement, does not require lofting your cue out of your bridge or high in the air (although you can do so as Scott and I had observed) and is better shown and demonstrated then tried, especially if we're off on the wrong foot. I'm happy to Skype with you and show you--no cost to you, this is not some pool lesson I'm charging you for.
You are very bright and know a lot about the game. I'm sure a chat online would add to both our knowledge bases.
Thanks!
