Dave,
You say "there are logical explanations for why some people think they get more spin with an LD shaft.", but your link has little meat.
This comment, "Now, when comparing cues and/or tips, it is important that the actual tip offset is the same for both." stands out to me.
Its important if you are trying to teach a physics class, but much less important when selecting equipment and using said shaft to play the game.
I find my Tiger Pro-X shaft @11.75mm to have enhanced spin for a couple of reasons.
When I aim my shot with a tip of offset my perception is that I am much closer to center than what is needed with a larger tip. For me
this makes aiming easier, more natural and less likely to miscue or just misjudge my shot especially the more difficult shots down table, thin cuts, or any shot where I want to load up on spin.
Weather my actual tip to ball contact point is the same or not does not matter so much to me. What matters is making the ball in the hole and getting shape.
Another enhancement is my ability to allow for squirt is at a manageable level, leaving a few more brain cells available for other tasks, allowing a more confident stroke. If not for this, my ability to spin the cue ball and would be very limited on certain shots.
I think factors that are difficult to explain and quantify scientifically are too often minimized in relation to player performance, e.g. hit, feel, perception.
It may be the Indian and not the arrow, but if the Indian perceives his favorite arrow is easier to hit his prey, then he will be more successful.

The "low cue ball deflection" (AKA "low squirt") part is true, but the "enhanced spin" part is mostly a bogus marketing claim; although, there are logical explanations for why some people think they get more spin with an LD shaft. For more info, see:
Also, LD shafts have both
advantages and
disadvantages.
