I just bought the OEK set for our Durango. 4 Rotors and all pads. $236.60 total. Will be here Wednesday. Awesome price for these. I was going to go with the Z23 kits, but I don't think I want the clicking noise of drilled & slotted rotors again.

Not to mention how goofy an idea it is to remove metal from a heat sink so it looks racier.
Drilled, yes. It weakens the rotor and while it used to be useful for out-gassing, that's no longer an issue with modern pads. There's still a bit of use for them in wet conditions, but that's pretty limited. Slotted rotors (properly designed ones, anyway) will divert water without the multiple points of failure created by drilling holes through the rotor.
Slotted, you're quite wrong. NASCAR uses slotted rotors (see pic #4 here [superstreetonline.com]). Wilwood recommends them [wilwood.com]. Slots help shed water, remove brake pad material, and deglaze pads. For daily drivers, the slots are almost entirely cosmetic (if you're glazing your pads in your daily drive, you need to quit driving like a maniac), but in performance applications with lots of braking, they're very functional.

Given he was talking about his durango he's pretty obviously using it for a daily driver, not a race car.
Which means I wasn't wrong at all, as you later admit in your own reply
Another reason to avoid slotted for daily use (besides the whole removing metal from a heat sink thing) is they still have stress riser issues as drilled holes do- just not quite as bad... this is WORTH IT for the benefits on a racecar that gets its rotors replaced very often anyway- but not so much for a normal street car.
