Even though I'm not a Bridge or FireRock fan in the least.
The S-03's look like a really good tire from what I've read about them.
I would go with either a KDW or S-03 myself. However since you think the KDW's are too loud that kind of narrows your choice down a bit...
Personally I can't hear the tires over the intake/exhaust or even the radio myself...
