	I have the cross drilled rotors and I don't think it reduced the 
weight of the rotor very much.  Certainly not enough to notice a 
difference in rotating inertia, or even holding it in your hand for that 
	Holding an Aluminum rotor in your hand however, is very dramatic. 
There is a huge weight difference.  Even more dramatic is holding a carbon
rotor in your hand!  I had a carbon rotor from the Chevy Intrepid GTP car
in my hands a while back.  THAT was impressive!  It was huge!  Probably 
13-14" diameter, and an inch or so thick, and I could hold it with one 
little finger!
