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

^^ besides the theory of hype, your, and the OP's, suggestions of that they are useless doesn't go anywhere.

you are both saying that no proof of benefits = hype, well then show us proof that it doesn't work and its function is hype. the burden of proof is on you and you have not delivered.

I can name half a dozen reasons why its better to have cross drilled, just as you can name half a dozen reasons why its better not to have them, so dont bother with that - go for the testing thats been done and show the results.

-edit- wanted to mention, a well known fact of drilled or slotted rotors is the holes allow the gases and dirt to pass through the hole, versus piling up between the pad and the rotor acting like ball bearings, this allows a much better "bite". I wanted to point this out because you said it gives less grip due to less surface area. The same goes with heating, less mass for heat dissipation? where's the heat going to go if there's no air/gas moving through transfering the heat? thats where the holes come into play - more air movement = less heat. You dont need rotors to prove that, look at any part that creates heat and how it removes the heat.
