Digital BW, The Print

I'm using a C86 with MIS EZ inks, (Photo Black, Neutral, Neutral, Warm), 
and I like the image tone that I'm getting, but I haven't found a paper 
that I really like yet. So far I've tried Epson Premium Glossy, Kirkland 
Signature Glossy, Epson Enhanced Matte, and Permajet Alpha. The best 
results so far have been with EPG. The Kirkland paper looks good, except 
that it's too glossy. (I tried printing color photos with it on another 
C86 with Durabrite inks, and they looked horrible! The prints were way 
too contrasty and oversaturated.) The Permajet Alpha printed with 
blocked shadows with my test image, and while I love the luxurious feel 
of matte papers, I really miss the tonal snap of glossier papers. I'll 
have to get some more of this paper. Finally, I had some problems with 
posterization with the EEM. (This posterization didn't appear with the 
other papers.) 

So I'm looking into what to try next. One option would be to try premier 
art spray on the glossy papers.  What does this do to the gloss level of 
the papers? Another option would be to try some of the Epson premium 
semi-matte, luster, and semi-gloss.  I've seen prints on the luster, and 
they looked very good except that they had more texture than I'd like. 
Does anyone have any opinions on the semi-matte and semi-gloss?  
Finally, is there a way to get small samples of these papers?
