After installing the new feed my 743/FA and CON70 converter inked with Pilot/Namiki Blue wrote straight away. Now I have noticeably better ink flow and reserve. Compared with the original plastic feed, I can flex faster and longer before the nib starves. In-fact on good quality virgin (no recycled content) 80gsm office bond I have to go flex-crazy in order to get railroading or hard starts. Again, this is using my favorite ink – Pilot/Namiki Blue. The new feed fits the nib and pen perfectly. The end of the new feed does not hit the paper when I am flexing the nib. Note, the flat sections on the rear of the feed that receive the tabs at the back of the nib allow for a little movement of the nib in and out of the section (at least mine do). This allows for a small amount of flow tuning by pushing or pulling the nib in or out of the section. However, I just left my nib pushed all the way back.
