Digital BW, The Print

I currently use a CIS (nomorecarts) with Gen4 inks in an Epson 1160 
to do all my printing. I'd like to do some occasional quadtone B/W 
printing too.

I've seen some information here about switching between CIS systems. 
But is there a practical way to switch between a CIS system and some 
MIS prefilled cartridges in an 1160? I just don't think I would have 
enough printing volume to have 2 CIS systems.

Thanks!
Phil
