Digital BW, The Print

I recently saw the 'Stonehinge' portfolio system at the local store, 
but was unable to get a look at the paper. The book itself is 
attractive--black canvas, instead of yucky faux leather. It appears 
to be manufactured by Lyson, as the packaging speaks only about Lyson 
ink compatability.  Has anyone tried it with the MIS UT inks? How 
does it compare to the Moab/Entrada portfolio? I haven't been crazy 
about Entrada--the blacks don't seem to pop as much as they do on 
Photorag.
