Digital BW, The Print

Hi--
I am relatively new to this group, so I hope that this is not "old 
stuff"

I have an Epson 3000 converted to Cone's PiezoTone inks (currently 
the warm-neutral, but switching to cool neutral), using his export 
plug-in.

I really like a nice white high light.  So far I have been using 
Legion Photo Matte in 13 x 19.  I really like this paper, but it 
doesn't seem to come in 17 x 22 size.  I have been using Somerset 
Photo Enhanced for this size, but the paper is not as white.

So my question is whether there is another paper that I should be 
looking at to give nice white high lights and which comes in the 17 
inch width?  The other requirement is that it be one that has be 
profiled for the older plug-in.

Thanks,
John
