I am about to purchase a vast ammount of printing paper. I am wondering about the Epson semigloss vs the luster. I love the simi gloss (provided in the samples with the printer). It reminds me of Ilford Pearl photopaper. The problem is that there is no 11x17 (Why?!). Are the differences very great, I was thinking of getting the 8.5x11, and 13x19 in semigloss, and the 11x17 in luster. What are the main differences between these two? Should I just get all my paper in luster?
