Digital BW, The Print

Several years ago based on Paul's recommendation, I started using
PrimierArt Hot Press fine arts paper (205gsm) on my Epson 4800 w
Ultrachrome inks for B&W printing.  My eye definitely prefers the
off-white (aka "natural", no optical brighteners).  I am using 17"
wide rolls and 8.5 x 11 sheets.  The packaging, product #, description
have varied, but about 8 months ago I got several 8.5 x 11 boxes that
were not off-white: it appears identical to the "bright white"
version.  This is not a subtle difference.  The Rolls were still
"natural".  I obviously want consistency, and I'm bummed because I
really love this paper (great price too).  I haven't ordered recently,
so I don't know how this issue has played out.  It appears that Epson
does not offer their USFAP (very similar) in this size.  I wanted to
post before reordering just to maybe find out.  Any knowledge on this
issue, advice on similar products??  Thanks, Kip- Deep Silver.....
