Digital BW, The Print

Hello B&W Group,

I have a second printer (Epson 1290) available now for printing B&W 
(glossy prints) and for me it is still a difficult choice which ink 
to use, Lyson SG or wait for Mis UltraTone till carts are coming 
available.

I have Lyson Fotonic running on a Epson 1270 and wich is doing a good 
job for me on glossy papers.

Can anyone help me making this choice for B&W printing?

Thanks
