Don't be afraid to consider the Specialized Turbo Cotton in 26 with lightweight butyl or latex. Fast, they wear well, and the yellowish tan is very vintage looking to me.
I just posted my experience in a previouls thread so forgive me ifor those that already read this.
All my ride routes include lots of chip seal country roads. 2 seasons ago I bought a new Spec Roubaix full ultegra and road the stock Specialize Turbo (not S-works turbo) tires with light weight butyl the 1st year. I then bought and switched to Turbo Cotton tanwall last summer. What an amazing difference, smooth and fast. Then, I installed latex tubes and that took it to another level. Never flatted once and i'm sure luck played a part.
The cotton turbos tires got plenty of life left but I'm intrigued with tanwalls and wanted to try Vittorias since that was what I rode BITD. Couldn't find the Vitt Corsa "Speed" at reasonable price so I bought a pair of Vittoria Corsa G+ comp and I've got several weeks on them running light weight butyls. They're sluggish and I dont like the tread lines on the contact area. wish I couldve found the "Speed" version because that would've been in the same ballpark as the turbo cottons. I am now spolied because I road a combination (turbo cotton with latex) of something that the feel of running tubular back in the day. The Vittoria light tan sidewall is very cool looking though.
For those that appreciate the feel of fast tires as listed in the resistance tests and want a vintage tan-wall look.. don't be afraid to try those Speicalized Turbo Cottons. Lightweight butyl or latex.. they're fast, eat up the road vibration, and look good.
