First of all... thanks for the wonderful information Marc!  I didnt read who 
was the writer of the email but I knew it had to be you.  Thanks again!

In regard to the cross-drilled rotors.  While at the race track i noticed 
that a few of the guys with drilled rotors would spend time using a 
screwdriver to pop out the built-up brake dust in the rotor drill holes.  I 
thought that was interesting.  I then walked around and looked through the 
wheels of other cars to see if the rotor drills were plugged up.  Sure 
enough, many of them were but the drivers didn know that.  But the slotted 
discs seemed to be clean.

This makes me feel that the drilled rotors would be less then ideal for the 
track since these "heated gas" vent holes were not going to do the job after 
several hot laps.
