Digital BW, The Print

Is Hahnemuehle PhotoRag Duo, suitably cut down, a good, if expensive, 
note-card stock for the MIS VM Sepia-Neutral ink set? I send too few 
holiday cards for the expense to amount to much. And I need to learn 
to print on PR anyway.

I thought I might use both the heavier, 308-gsm PR Duo for unfolded 
cards (S-N image on one side and note on the other) and the lighter, 
196-gsm PR Duo for folded cards with a S-N image on the front. Any 
other printing I could do either with S-N or, on a second pass in 
another 1160, with MediaStreet Enhanced Generations with the Gen4 K 
replaced by the S-N K.

I assume the lighter Duo is heavy enough for folded cards? And that 
it folds ok in one direction or the other; does anyone know which? Or 
whether VM ink on the heavier Duo is scuff-resistant enough to be 
used as a postcard rather than in an envelope?

Are envelopes available in a complementary color? I guess a match is 
too much to hope for unless Hahnemuehle does them. I like Crane's 
envelopes partly because I find their square-flap "Announcement Flap" 
A2, A6, and A7 envelopes easier to print and write on. Either their 
bright, Fluorescent White (what a name!) or their Pearl White would 
probably be better with PhotoRag than Crane's warmer Natural White?

In addition to any advice about any of the above, I'd also be curious 
to know what those of you who print your own B&W-image cards do with 
other papers too.

Thanks.
