So I’ve ended up using a gel pen lately. It’s because the inserts I made to use my new leather notebook cover have Atlas Bond in them. Nice paper, but unlike most notebook papers it doesn’t take ballpoint ink very well, so I tend to gravitate to fountain pens or gel pens.
While I really like the line density, they don’t very long. I figure I’ll get a month out of the Sarasa vs. at least 6 months for a Fisher refill and more than a year for a Caran d’Ache Goliath.
