Krylion Carbon is just great for most of road biking. I use it for commuting, training, semi-races. It's overall performance is good, it resists punctures and lasts long. Definitely the best package around.
I ride the races with Michelin Pro2 Race service pack which roll *very* smoothly and still have a great grip. They're not even close as durable as Krylion Carbon, though.
