Digital BW, The Print

Hi group,

Just picked up some Epson Matte Paper Heavyweight. Doing a quick
comparison print (with QTR B&W), I don't see much difference from
Epson Enhanced Matte.  Looking at the Wilhelm site, the Heavyweight
matte appears to have very good archival properties.  

Those of you in the know, help me out.  What am I missing about this
Heavyweight matte paper ???  Couldn't find much on the Epson site.

It is much more economical than EEM.  

Thanks,

Tony
