I have about 1500 on my first set. I mostly ride Continentals, but when Michelin came out with the Pro4 series Chainlove had Krylions and Pro3 Race for ~$25 and I bought a bunch. I've mostly been training on the Krylions and some GP4000s that I had left from the previous year. I've mostly used the Pro3 Race for events and a few solo hill rides.
