They are both slotted and drilled--- 
 
So there may be some pad material build up on the rotors---and a couple hard stops will clean that off?  I will give that a try tonight.  I read through Stop Tech's info as well--they encouraged using Garnet paper and sanding the rotors to break off the pad residue---guess I will try both.
