I have used several sets of these tires over the years. I like how they feel and I appreciate their durability. I feel like they are strong, yet fast. I generally have them on my triathlon bike, which I train and race on, as well as my road bike, which I generally just train on.
It has been my experience that they are worth the money. I prefer having different colors, but black is good too.

Endurance road rider 3-4 times a week for a total of 150 miles a week in fast paced group rides over differing terrains on farm to market asphaltconcrete and chip-seal roads
I have only ridden about 400 miles on these tires. I find that they give a nice ride with gear control. They smooth out the chip and seal roads that are so plentiful in northern Indiana and glide effortlessly over newer asphalt. Love the red stripes too . The look great on my bike. I can't speak to longevity as I have only put a few hundred miles on.
Sure, you'll sacrifice a little weight, but you'll gain added comfort and flat insurance. After too many flats running race tires for training, I made the switch permanently. Race tires are for racing. Michelin's Pro4 Endurance tires are for every day. In short order you'll hardly notice a difference!
I used the 25mm version on wider rims (Pacenti SL25, internal width 20mm) on a disc road bike for commute, and had great results. This seems to have the smoothest rolling among other wintertraining tires I've used so far Continental GP 4 seasons, Vitorria Rubino Pro G, Specialized Roubaix Pro.
These tires strike a nice balance of everything you want in a general use training tire. They aren't race day tires, nor will they hold up to riding through a pit full of nails and broken glass, nor will they be an heirloom in your family for generations.
But they are cheap, comfortable, put up with the occasional road trash, and they won't wear out after 200 miles.
