Digital BW, The Print

Thanks for all the input so far. I'm beginning to think there are a lot of 
great papers out there ;o)

A few more questions if you can bear with me:

** Seems so many of the recommended and highly regarded papers use OBAs. 
There are some beautiful, expensive pictures being made on papers with OBAs 
and sold to collectors as digital gains credibility. And it's clear to me 
that many people making prints on these papers have *very* specific ideas 
of what their prints should look like. Are the makers concerned with what 
the prints will look like over time?

** Are the typical specs (cotton, etc.) for the papers that have been 
suggested enough to inspire confidence in their archival qualities? 
Ultimately it must be a wait and see situation, but most printers seem to 
be relying on Wilhelm's tests to some degree regarding archival issues. 
Wilhelm has actually tested few of these I think. Is it likely that an 
untested paper will fare as well as a tested paper so long as the published 
specs are similar?

** I'm wondering if there's a paper weight sweet spot (for me at least). 
The 190gsm range seems just a tad light, but I'm afraid the 300 range is 
going to make me jump through hoops feeding my 2200. I'd prefer to feed 
normally (through the top). Some of these papers come in what seems to me 
to be a good compromise weight of about 250gsm. Will this weight top-feed 
easily?

** Premier Hot Press has been mentioned a few times and it was on my very 
short list before I asked. Does it fall short in any way that I might not 
discover in short term testing of my own? Are there decent canned profiles 
available so I can test this paper?
