Digital BW, The Print

I print on all Photo Black type papers (versus Matte Black fine art 
stuff.)

I have never had a problem with curl, or needed to make an imitation 
d-roller. ;>)

The one paper that does have a fair amount of curl at first is the 
Innova Glossy.  But it flattens itself within one day if left to sit, 
as mentioned above.

I have standardized on 3 papers.  One for proofing - Epson Premium 
Semi-Gloss. One for everyday prints - Epson Premium Luster. And one 
for premium quality prints - Hahnemuhle Fine Art Baryta.

I only use 24" rolls. I have spindles for all 3, so they are all 
loaded and ready to go.  Quick and easy system that keeps me from 
having to stocks lost of sizes, etc.

The Hahnemuhle Fine Art Baryta in particular is much cheaper in roll 
than sheet.  

Best,
Michael
