I don't think slotted or cross drilled rotors really have any advantage in this application. In a racing application where heat-shedding is important, sure, but if you're stomping your brakes at +90% force every 20 seconds or so, you probably don't know how to drive
I used to have powerstop drilled and slotted rotors and actually burned through them in about 30k miles (worn to the point they were too thin to be used). Now bear in mind, part of that time was while my LSPV was outta whack. I also tow a camper without trailer brakes occasionally. But I felt no performance advantage to the slots or holes.
In the course of my ownership of those rotors I also got stuck in a serious mud hole at one point during a sloppy spring blizzard. I had to take the wheels off and spend a good hour or two with compressed air and various screwdrivers, etc, to get all the debris out of the holes.
So when they wore out, I got regular blank rotors. Just one guy's opinion
