Tyres that grip in the wet are much cheaper than new kit or time off work and time with the dentist, so I standardised on Veloflex Carbons last year, before that I used Michelin Pro race 3. According to Tour tests Conti GP4000s or Attack / Force are the best, so I will try them next.
Back when I raced on clinchers I used Attack/Force and (old pre Chilli) GP4000
I think the Attack Force combo is really underrated, I only had one set of wheels and they did everything without a problem, not too many flats either.
Only reason I have Gators on the wet bike is because I don't care about the extra weight for training and wanted something that just kept going.
