Cross drilled are made for everyday use, and provide less glazing and cooler operation of the brakes. The slotted rotors are designed for the racetrack. There entire reason for development was to give the driver a consistantly renewed braking surface on the pads. These slots were designed to shave a miniscule amount of surface off of the pads each pass to prevent glazing and decreased performance. The fact is that if they are true slotted rotors you will see a quicker rate of pad wear, but some people like the looks of them and put up with this. To each their own. I like the looks of the cross drilled/slotted rotors, but am going to go with the cross drilled only myself.
