My fine nib TWSBI Eco is my go-to for note taking for work meetings. I usually have it filled with Pilot Iroshizuku Asa-Gao, Shin-Ryoku, or Noodler's Ink Dark Matter. I've tried Noodler's Ink 54th Massachusetts in the Eco, and it wrote a line one size up. Fantastic ink, but you have to know what you're getting into. It wants to charge out of the pen and onto the page, so even with the Eco, I had to have it in a pen cup, nib-up when not in use. (I have the pen horizontal on my desk top or in a drawer when inked with other inks.) I, too, can highly recommend the TWSBI Eco. It is definitely worth every penny of its comparatively low price.
