Digital BW, The Print

Anyone with experience printing to Somerset in text weight from 
an Epson (or other) printer? I'm hoping to find a paper suitable 
for photo quality inkjet printing in an Epson 1280 that is 
lightweight enough for use in creating a hand bound book. So far 
Somerset is the only sheet I've had recommended that is 
available in less than 165 g/m2 weight. I'd prefer an acid free 
sheet with at least moderate archival qualities.

Thanks
