Picked up my bike from the shop yesterday and the chief technician told me they called Cannondale, they said to replace the rotors with a set of Avid rotors. They did this and the technician said he rode my bike for a total of about (6) miles that afternoon with no squealing or squeaking. He said that this set up should work great, only time will tell!!! I have not been able to test ride the bike for myself, been sick. We'll see what happens next.
