Lamy Aion

I like the look of the Lamy Aion, but the cap rattles. I like the look of the Lamy Studio, but the clip scratches the pen and the finishing gets damaged when you post the cap. I like the design of the Karas Kustom V2, but you can’t post the cap. I like the general look of the Faber-Castell Loom, but not the smooth and glossy grip.

For me it's that next level pen, the one that you choose based on how you've learned what you like and dislike, and what your usage case is. A pen that you've spent time researching, maybe even tried before you dive in yourself. Generally slightly more expensive and durable, or just more practical. For me it was a Lamy Aion.

Pens that I have out-grown: Lamy Vista, Lamy Al-Star, Lamy Aion, Pilot Metropolitan, Pilot Kakuno, Jinhao 159, Nemosine Singularity, BirminghamPens (metal with #5 nibs), Jinhao X750. The Lamy Studio is right on the edge, hanging by a thread, because the nib is not crisp enough, now that I prefer Cursive Italic nibs.
