OK OK, let's get serious. My personal favorite : Lamy 2000 fine nib inked with Rohrer & Klinger Dokumentus. Most times to complement it there's at least one Parker 51 as a quick note taking pen / highlighter (puts out way more ink, so some cheaper papers don't really work with it) and one or two Montblancs (mostly inked with Rohrers Salix) just for the fun of it.

I haven't quite settled down on paper though. Rhodia wire-bound dotted A5 has the best quality paper, but I sorely miss the flexibility of free leaf notes. Latest discovery - Muji's A5 binder. It's a Japanese 20-holes-per-A5 spacing, so fairly rare in the EU. Also, the Muji's default paper isn't great for some wetter fountain pens... but hopefully I'll figure some way to make it work.
