My Lamy 2000 is my favorite pen. Writes fantastically well and is made so well. I use it every single day. Thanks for posting these videos. I learn a lot about writing better watching them. Update: I recently dropped my Lamy onto my desk from a height of maybe a couple of inches and destroyed the nib. It is incredibly fragile.
to Jeff Ashe: I am unable to reply to your comment directly. The paper in this video is a local brand, called Aisling. It's very cheap but minor bleed/feathering occurs with wetter pens, such as the Lamy 2000. The ruling is 8mm, which is the standard. The medium nib is perfect for me. Broad enough that it's fun, and fine enough that it's practical. I wouldn't suggest the medium if you use cheap paper, however.
