Not to discount anyone else's personal experiences but here's mine:
I've kept track of mileage now and gone through, back to back, a set of Continental Comps 22mm and a set of Veloflex Carbons 22mm. Have to say, I found no noticeable difference in wear. And I think for me at least, it would appear that I need to think about replacing the rear, regardless of brand, somewhere between 1200 and 1500 miles (~2000 to 2500km). I weigh 195-200lbs (88-90kg).

Thanks for sharing your experience. I think I may change my sprinters for sth better, but first they have to get worn Vittoria or Veloflex would be my next choice for training tubulars and probably FMB for racing ones. I weight 72-74kg and I rather don't skid my rear wheel. Roads are rather good here, but if opt for less traffic then I get worse roads with more debris on them.
