The good majority of the folks here are running skinwalls or blackwalls on VLW's (or Conti's red wall), and hardly any qualify to be an extreme-performance tire. Heck, hardly any 27"-wheeled machines from factory were intended for performance; they were sport tourers or tourers - bikes made for a tire such as the World Tour, Pasela, or the Armadillo. Fact is, if you've got 27" rims in the first place, chances are you're not looking for performance exceeding that of any of these three tires.
