Digital BW, The Print

Hello, as it is OT here, just in short form:

Has anyone achieved satisfying (equal to OEM Epson) results with the 
MIS version of the Ultrachromes, eventually after having custom 
profile(s) made? 

Having recently purchased the 2100, I actually try them out in 
prefilled cartridges, but am not yet very happy. Not bad, but just 
not as good as the originals.I would like to be sure before buying a 
CFS for them, as this is quite expensive.

If you think this is too much OT, feel free to answer me with private 
Email.

Thanks for any input,

Bernhard
