I've used nothing else for several years now. Due to lapse in the routine maintainance of my bike, I reckon that I rode a 120km Audax with the rear tyre down to canvas - a recently fitted bottom bracket dynamo had accelerated tread wear.....
The version I buy here has a black sidewall, it seems to hold the tyre together better and of course the sides don't stain with brake crud and oil.
I do check for obvious defects but I find that when worn out it's pretty easy to tell because they start puncturing quite regularly. In fact the last set didn't punture once in normal use until completely knacked.
As I said before great tyre. I can't understand why so many use those 600g+ clunkers on their commuters. As a bonus too the flexible sidewalls mean a better ride than the heavyweights.
