I've not ridden the 50, but have the 42s and ridden plenty of miles to say they are a plush all around tire. They aren't speed demon tires, but they will get you from point A to B and back with no issues. Even though the pair I bought were PRE-tubeless, I was able to set them up with no issues and they held pressure just fine. Unless you are looking for a fast rolling road style tire, you would be very happy with your purchase.
