rotor disc performance questions, inquiring minds want to know Options

[orange914]

O.K. so disc brake performance has so many different aspects. Add your experiances and wisdom to the question below

Starting with the solid vrs. vented... venting, heat, weight, stopping performance, off gasing, strength

My main question is what exactly are the performance pro's & cons of each:
A] slotted
B] dimpled
C] cross drilled

Summit refered to this and it made my wonder (IMG:style_emoticons/default/confused24.gif)

Motorcycles use steel rotors, not cast iron or sintered steel, so they can get away with drilling, or through slotting. I agree with the no drilling of stock rotors, but slotting can be done on both manual or cnc machines almost equally easilily. The spiral slotting is a whole lot easier on cnc. I do have a guy local that can do them in his garage, he has a decent cnc bed mill in his garage if you need it done.
