An additional problem with the holes, whether they are drilled or cast (though cast is better) is that they act as stress risers in the material. As for weight I don't think the holes make a significant difference.
Weight is always a trade off on rotors... you want to reduce unsprung and rotating mass, but more mass in the rotor means it can absorb more energy before getting too hot.
