Ate Power slots make some noise, very mild, but someone told me that they wear through pads quick. We shall see.

the zimmermans that i have for my 560SEL front brakes appear to have cast holes. So far I have no craking and I have about 10k miles on them.

for one stop, I think the blanks are better because they have more contact area with the pad vs the drilled (perforated) rotors. The slotted ones are kind of like razors coming by each time to eat the pad. Thats just what I think.
