Digital BW, The Print

Man, I just got my sample pack of Silver Rag today when I returned from being out of town 
and I leave town again tomorrow, so I won't have a chance to test it out for another week.  
But these initial reports are making me want to squeeze in a half hour at the studio today 
between unpacking and re-packing to knock out a quick print on this paper on my 4800...

Have any of you compared Silver Rag directly to a print of the same image on Hahn. Photo 
Rag Satin using K3 inks?  For B&W, that's been my paper of choice for the last few months 
and it's very good (except for the overly textured surface).  I wasn't blown away by it for color 
-- I mean, it was good, but not radically better than what I'm already using for color (innova 
Smooth Cotton).  I'd be very interested to hear comparisons of Silver Rag and Photo Rag Satin 
for B&W work.
