The Continental Grand Prix series of racing clinchers is the top choice of serious race bike specialists all over the world, and has been for many years. The latest incarnation is the Grand Prix 4000S.
"I usually ride Continental GP4000s but i thought i would try something different. I had read mixed reviews - most would agree they are fast tyres but there are a fair few who claim they are prone to punctures. I never punctured on my GP,s (3 sets) and assumed those who had on the these were just unlucky. In the interests of free speed i bought some. First ride and about 20 miles in the back tyre blew (sidewall) whilst i was doing 40+mph. I have just ordered a new set of Conti's."
