Digital BW, The Print

Hi, I've been using MIS Eboni in my old Epson 1160 for BO prints with
great success.I usually use Hahnamule Photo Rag 308.I was thinking of
trying MIS's photo black and some Epson Premium Luster with BO, so,
does anyone have experience with MIS photoblack and BO printing on
semi gloss or luster papers?If so how are the blacks compared to Eboni
and matt?

Thanks.......Chris
