I also use the non-drilled Brembo replacements, and they work great (especially with the ceramic pads). Low dust, no noise, awsome pad and rotor life, and great stopping. Putting on drilled or slotted rotors on this truck would be for "show off" purposes only. They may look cool, but will provide no braking benefits, and will actaully result in lower pad and rotor life, as well as more dust (due to the "cutting" action of the holes and slots). In actuality, no vehicle benefits from slots or drilling on the streets. It is only in track situations that the benefits of these rotors come out, due to the extreme stress brakes are under in repetitive track braking situations.

I doubt anyone is tracking their ML--even an AMG.
