Greetings one and all, So, I've got a Lamy 2000 (F-nib) which I want to "induct" in my EDC. It'll be required to sign documents etc. and also write on varying grades of paper, some of very poor quality. I'm thinking of using Noodlers Bad Belted Kingfisher, which I like, but which gives me nib creep on my Pilot VP (M-Nib) and so I expect it to do the same on my Lamy 2K (F-nib). But in an ideal world, I would want a "safe" forgery-proof ink (similar to that in a Pilot Signo 207 series Gel pen) which doesn't give me nib creep on my Lamy 2000. I know R&K has document ink (Dunkelblau, for example) which seems similar in performance to the Noodler's warden series; then there's Diamine with the Blue-Black Registrar ink. I could also consider the Mont Blanc Permanent series. Any thoughts..suggestions?
