Digital BW, The Print

I'll soon need to order a few hundred sheets of 13X19 Moab Entrada
Natural (or similar)...I should sample some other papers first.

I have zero "flake" problem with Entrada...air-blasting eliminates the
culprit dust (apparently a problem in a batch last year)..Entrada
seems otherwise very resistant to abrasion etc. 

What other *relatively well known* (for marketing purposes), heavy,
natural, matte (minimal texture) papers would you suggest that I
sample, given that I will only be using OEM Ultrachrome?
