Lots of guys at Alpenrose (particularly sprinters) use Vittoria Pistas for race day tires where durability is not a concern, and the CS is Vittoria's new "concrete track" tire. If you want a durable tire that also performs well as a race tire, I'd go Vittoria Corsa Evo CX (their top line road tubular). It's what was recommended to me and it's worked well for me over the past couple years.
