Having just read the harsh inks thread (yes, I'm behind the times) I thought I'd try to post the information sheet I got from Pilot. I was concerned, after reading Richard Binder's site, about my Omas celluloid. If I understand them right, their inks vary between 8.5 and 10.5.
Upshot: Aurora and Visconti (and occasionally J. Herbin) in the Omas from then on. Better safe than sorry.
