Digital BW, The Print

Any one tried the PermaJet papers from MIS?  About to order some 
replacement Eboni carts which I use with my 2200 for BO printing and 
thought I might try some of this paper.  In particular the Matte Plus 
Classic.  They also have matte papers called Artist Classic, Museum 
Classic, Parchment Classic and Portrait Classic. Anybody know more 
about them or how they are for B&W inkjet printing?  Is the Matte 
Plus any better than Epson EEM?  Thanks.  Richard
