The difference I was talking about was feel, than any speed/rolling

 Given what I've read about violins (Stradivarius can't be told from modern ones in blind hearing tests)

horseshit. Someone with training and experience can most certainly tell the difference in the tonal quality between a Stradivarius and even a high quality modern violin.

and wines (cheap wines really light up pleasure centers in the brain if tasters are told the wine is expensive),

more horseshit. Someone with training and experience can certainly tell the difference in the flavor profiles, especially if you tried to dupe them with a Gallo.

I'm somewhat skeptical of a lot of "feel" judgements regarding bike tires - and bikes.

That's certainly your prerogative to be skeptical, but given that there are indeed people with training and experience who can tell the difference between a Stradivarius and a Scolari, as well as between Don Melchor and Crow Canyon Cabernet Sauvignons, I have no doubt there are individuals who may be able to tell feel difference between various quality TPU tubes.
I definitely don't qualify for any of the above, but know there are people who do have those talents.
