Advantages to slotted or drilled rotors? I don't think so.

I read this post a few times and thought about it for a day or so. First off let me say that I can tell that you have put a lot of thought into the cross drilled slotted rotor topic and that I have no desire to start a rotor war. I have on past cars run both. I can honestly say that on my 92 Corvette that when I swapped out my stock 13 and 12 inch (big in the day) rotors for cross drilled that there was a measurable difference in both pedal feel and performance. They brought me down from 125mph to 35mph many times without bluing or cracking. I have seen cross-drilled rotors crack. I just have not have them crack on any of my cars. My first set went on with new stock pads and stock lines. You can definitely feel the initial bite when you get on the brake. After going to Ferodo pads (do they still make those?) and Russell lines performance was even better.
I've also run slotted rotors. I might run those on the Z. I haven't gotten that far into my build plans yet.
