The way I identify a Pangit thread is it has Pangit's name on it.
Now that we have that nonsense out of the way, he poses a question that should be of great concern to cue makers. It has spawned a multi-million dollar sub-industry in golf which is called club fitting and yes, it does make a big difference. Playing with a properly fitted set of clubs will make you more consistent immediately.
I see no reason this principle cannot be applied to pool. Many years ago, when I was a trumpet player, I was shopping for a new horn and I came across a kit for a horn called an Olds Custom. The kit was a couple of cases. Inside were a few valve bodies of various sizes, different bells, lead pipes, etc. They fit together with screw clamps. You could mix and match different components and assemble a horn you liked. They would then take down the numbers off the components and send them to the factory and a few weeks later, you got the horn you built.
A cue fitter could meet you at the pool room with a couple of suit cases of components and fit you. Length, balance, weight distribution, shaft taper, butt taper, grip style, on and on. You could get all of that settled and have a printout of your custom specifications to hand to the cue maker of your choice. It would be a lot cheaper than dropping a thousand on a cue, playing with it for a few weeks and finding out something about it bothers you and wind up selling it for a loss. It doesn't matter how well a cue is made, if it doesn't fit you, it is not worth it. If I were a cue maker, I absolutely would be doing it. The one size fits most approach has gone on long enough.
