Digital BW, The Print

Please excuse me if this question has been addressed before. 

I'm  considering purchasing the UT7 inkset for my Epson 2200 printer
in lieu of upgrading to the 2400 and using K3 inks.  I realize that
this is for B&W printing only, but I'm curious how the Ultratone inks
stackup against Epson's latest K3 technology.  I print primarily on
Enhanced Matt or Velvet Fine Art paper; I don't print glossy or luster.

If I do stick with the 2200, I'll proably buy the 1800 for my color
printing needs.

Any comments would be appreciated.
