is it your experience that the venting doesn't matter as much as just having more mass?

There is a couple of things that go in a rotor. Internal cooling, what type of cast iron, how it's cast, hardness of the cast iron. Some rotors are a powder that is put into a mold and cooked until it's molten. Then left to cool.
