Digital BW, The Print

Ok, made a bunch of 7660 prints on the hp Premium Plus glossy that 
look really good.  The driver is very accurate and the tonality of 
the prints is great.  Everyone I've showed them to thinks they look 
better than my 1160 MIS VM mw prints (hard to accept given all the 
effort that went into making them)... and this is after I go out of 
my way to point out the slight greenish tint under certain lighting.  
The depth of shadow detail is significantly greater than I've seen 
out of pigment prints.

The thing that concerns me is that the paper seems to like to buckle 
and curl so just hanging the prints behind a matt is not going to 
work.  How has anyone mounted this stuff?  Is that funky weird stuff 
on the back a problem?

thanks in advance,
