Actually I took a second look at the negatives and I might have to agree with the previous poster somewhat. There are definite areas of clearness and if the CLS were uniformly there you'd get the brick factor going on.
When you get the pot-ferri run a few bleach tests on one of the strips. If you see no change then its definitely not a bleach issue.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
