Digital BW, The Print

Hi all,

Here in Australia, Epson has a R290 a 6 Color printer. Will be getting 
a CIS for it. I plan to do only B&W on the printer, so I was wondering 
what sort of B&W 6 ink to get from inksupply? 
Looking at the list http://www.inksupply.com/qn.cfm
there is no R290 in the "6 Color Printer" list. 
I presume I could use the R200/R220 or R260/R380 inks? 
Perhaps the R260/R380 is the one closer to the R290. 
Though a question in my mind is why is "UTRC" is only available and not 
the EB6 ink for R260/R380? Would it matter if I got the EB6, or would 
there be an issue with the ink clogging?
Thanks
