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. -- Add xx to reply
