Dye or Pigment Ink for 3880 Question

I recently purchased a Epson 3880 to print on only one type of media a heavy matte paper. I will only be printing full color graphics no pictures. I am not concern about life span but I do want the best colors possible for the paper media. Does anyone have a suggestion for which type of 3rd party inks I should be looking for, Dye or Pigment? I saw that there is Ink Thrift for dye is there any others that make a dye ink?
Thanks in advance for any help!! I am so glad I found this forum!
