It's time for me to buy a new set of front rotors. Anyone have any comments on the difference in pedal feel between a normal
slotted rotor (which I've been using) and the crescent "slotted" rotor as on this RS6? Any other differences?

more pad grip from the more abusive crescent design vs. the straight slot.
The crescent pattern will sound more like a cross-drilled disc when stopping.
I would expect you to notice the following:
1) More pad dust
2) Less pedal feedback under hard braking
3) More disc "moan" under hard braking
4) Slight increase in pad grip?

I'm a bit surprised, though, that the crescent pattern rotors from both Alcon and Brembo (with a similar design) seem to be popular on track if they reduce feedback. You mentioned hard braking, is feedback more comparable with lighter braking, such as when trail braking?
And speaking of rotor noises, my favorite is the loud shrill whistle from the drilled solid rotor of our Formula Continental.

...I find I have much better "feel" at the limit of ABS with the the segmented pattern. In the straight slots, I had difficulty distinguishing between Audi's slow ABS system, or just pulsing from the slots.
I should clarify, when I say "feeback" I'm not saying "the ability to feel what the discs are doing", I mean "the pulse in the pedal from teh straight slot"
Maybe that clears it up?
