I'm about to tempt fate by switching out the Randonneurs for some racing tires. The Randonneurs have been amazing: Seattle's pavement is crappy as hell and I've run over glass, metal shards, ridden on a lot of gravel, and I've had no problems with around 4K miles on the set. They are heavy though, thus switching.
