I’m a fountain pen user (helped me tremendously with RSI), but the Pilot VP <F> is my daily driver for note taking — it’s retractable. Other frequently used pens: Kaweco Sport (Brass) <F> as a pocket pen and a Pilot Custom 823 <M> for letters / sit down writing.
These are all excellent fountain pens! I'll add the Lamy 2000 (Fine nib) to the list, as it's my personal favorite and is what I use all day every day. And I happen to also use a Pilot Custom 823 (Medium nib) for journaling every morning. Nothing beats a nice fountain pen with quality ink and paper. Speaking of inks, I've found Rohrer & Klingner's Schreibtinte Verdigris to be wonderful in the Lamy 2000, and lately I've been using Noodler's Sequoia Green for the Pilot Custom 823.
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.
