In my fade testing I've seen no correlation between brighteners and fading.

Also, while many seem to think brighteners are a negative to longevity, I've
seen no hard evidence that they reduce the paper's life.

I'm not sure there is any negative to brighteners aside from the fact that
they will eventually "burn out" and cause the paper to yellow a bit.  In my
tests the typical yellowing is about 3 units of 256, then the papers
stabilize and do not further yellow.
