Rolling Resistance focuses on watts and puncture protection but they can't measure ride quality.
IMO Vittoria's second tier Rubino is equal to either the Michelin or Conti top tier tires.
Supple and forgiving, never twitchy or bad mannered. They love being driven to the limit and will never scare you. The "Speed" version is really fast if you don't mind a somewhat shorter lifespan.
