Yuppers! I just received my order, piano black in EF. I was at an annual pen sale event hosted by a local store, where the Lamy rep told me that the EF grind in 14k only is shaped like an architect’s grind, and let me try it with his personal copy. The skies opened up, angels were singing, and my eyes were wider than a Anime character. At the $300 range I wasn’t going to buy it, but the Endless Pens deal was too good to pass up. I did buy another pen from the store.
The rep did recommend using an ink with more lubrication. He used a Sailor Jentle. I used Caran d’Ache and it works just as well.
