Digital BW, The Print

Has anyone on the list any experience of using the Lyson black inks. 
Has anybody used the small gamut black inks that allow toning and 
split toning effects with the same inks instead of using their 
cool/neutral/warm black inks. 
How do they compared with the PizeographyBW system.
What paper would people recommended for B&W, I have been using 
PermaJet Museum Classic printing on an Epson 1200 with just the black 
inks. The results are OK, but I would like much better quality to use 
in Club competitions.

Any help or advice would be greatly appreciated.
