Digital BW, The Print

I got my first box of Harman FB AI Gloss today, and tried a couple of
prints with my R2400.  I normally use a color-managed workflow with
the appropriate ICC for each paper I print on.  Up until today, I had
only printed on matte papers (PA 205, Photo Rag, William Turner, etc.)
and have been satisfied with the results this workflow produced.  I
use Epson Enhanced Matte for proofing before making the final prints.

I've been wanting to try an F-type paper for some time, so after
reading reviews I chose the Harman FB Gloss.  I don't have any other
glossy paper on hand, so I didn't have anything to proof with.  So I
just used my normal workflow: Photoshop manages color, Harman Gloss
ICC profile, perceptual, black point compensation.  In the Printer
Settings I selected "Premium Glossy Photo Paper", "No color
management" and "Best Photo".

The results were completely different than what I see on my screen. 
Both prints were significantly darker, and all of the detail and
variation in the darker tones was completely lost.  With the prints I
was making on matte papers, I was getting pretty good WYSIWYG results
and only small adjustments were necessary.  

Here's an example of what I mean (sorry for the quick & dirty scans -
I was in a hurry):

I'm still a novice with all of this so any help you can offer would be
appreciated.

Thanks,
