Digital BW, The Print

i typically print on Epson Premium Semi-Gloss with MIS FSN & PK, but 
am interested in trying Premium Semi-Matte.

 since it only comes in rolls that i'd have to cut, and can cost a 
bit, can anyone offer a comparison of the two? (D-max, brightness, 
finish, bronzing, longevity, etc....)

 can one use Photo K with it, or is Matte K or Eboni required?

 thanks
