Familiarity: I've put it through the wringer
Disappointed in the ride quality - not very supple, even at a lowish-for-me 100psi. Seem to roll out fast and corner okay, but I find some of the Veloflex or Vittoria offerings superior...and at a lower price. Not a bad thing these fit on the tight side - just prestretch and warm them up a little beforehand. I managed 1,800 miles with a midway rotation. No punctures.
