David, so you're still out there somewhere?
I wish I knew some answers too. The only possible useful comment I 
have is that Torchon, and it's equivalents, seemed to yellow faster in 
Steve Meyer's window tests here than the other Hahnemühle papers. One 
could assume that the only difference is brighteners, but who knows?
Since many seemingly harmless things occassionally degrade inkjets, 
I'm suspicious of all this stuff, I keep trying to make it work to my 
liking on uncoated art papers, rather than inkjet papers. I haven't 
done it yet.
It's interesting that many of the dead guy's prints that seem to glow 
off the museum walls, or platinum prints, have none of these things in 
them.
If you discover any useful info about this I hope you post it.
