Digital BW, The Print

Hi-

I'm about to take the plunge and move to CIS. In this case, 
nomorecarts and FS inks on an 1160.

Any advice on what size bottles of ink to buy?

My instinct is to forget about any quantity savings and get 4 oz. 
Bottles so the one you install is a "full mix" and not a problem.

Thanks,

Tom O'Connell
