I'll tell you what ...

I've ridden Vittoria exclusively for the past several years, from their cheapie Nuovo Pro and Rally tubulars on an old track bike (stolen in 2000, major pout), to their newest Corsa EVOs on my Richard Sachs.

I've got 3 full sets of wheels between my Cooper, my Sachs, and a spare set ...

So here's what I propose:

Send me a few pairs of the various models you have, and I'll pull off all my Vittorias and give the Tufos a fair test on 2 different bikes, with 3 sets of wheels, and I'll post my findings here.
