Digital BW, The Print

Hi, 
... yes, an other "inkquestion".
I'm looking for "my" BW ink system with Epson Stylus Pro 7600. The 
last three month, I think, I did nothing else than surfing thru the 
internet and looking for the perfect ink. 
So, the result?  I'm totally confused and have no Idea what system 
would be the best for me. The entire Manufacturer say that their 
system is the world best you can get. 
During my web research I found 5 different Inks. Maybe there are a 
couple more then 5.

Sundanse Inks (also for 7600)
GQ Generation QuadBlack (not for 7600)
Piezography K7 (for 7600)
Lyson Quad Black  (not for 7600)
MIS UT7 (for 7600)

As there are some inks not available for my 7600 Epson, I think I 
want to decide between the Piezography and MIS Products.

The Pro of MIS is that they are for both, Matte and Glossy Paper, 
right?


Maybe somebody could help me in this decision?
Please tell me your experiences with you system, so that I can 
find "my perfect BW ink" :-)

Cheers 

Florian
