Eric, Yellowing may or may not be the same phenomenon as loss of
whiteness. Some think they're both a concern, you may not: Eye of
beholder. 

The current Polar White is said to be a new formulation...that's why I
questioned your length of experience with it. 

I meant no disrespect. don't doubt you've had many years of experience
with an earlier formulation.

The only information I have on whitening is in the perhaps-valid 
marketing information of paper distributors. Moab, for example, has
stated in its marketing that whiteners were moderated in Entrada
Bright in order to minimize changes, implying directly that whiteners
were problems for people who wanted maximum stability.

Eric, If you can link scientific information on whitening, please do. 

I'd like to know why one 100% rag paper would have problems with
whitening and another would not.
