It works! I can use my PS5 controller with #ffxiv on the Mac! No more having to stream the game from my PC via Steam!
I also changed the nib on my second Iris to the 1.1mm stub (sadly just the "generic" appearance, not the Iris-look), and filled it with J. Herbin Amethyste de l'Oural (basically purple with a slight silver glitter) for Husband to write a note card for one of his staff.
I think he's now convinced I have some kind of Magical Fountain Pen Selection mojo (he has big handwriting and I don't think he's ever used a stub nib before).
I have finally found an ink that does not bleed through my journal pages: Noodler's Bulletproof Black.
It's not as "black" as the X-Feather but it dries/fixes quickly, holds up reasonably to highlighting and, as mentioned and most importantly, does not bleed. So... winning.
I also tried the Pelikan Brilliant Black which was... honestly terrible? Grey and "splotchy", smeared under highlighter, *and* it bled. Do not recommend.
In related news, I still don't love the Mildliners; the ink feels really meh compared to the Tombows, and it colors really streaky (fortunately the Tombow blender, of all things, can smooth out most of that, but...).
So they're okay for, like. Actual highlighting (single line/single color) and so on, but they're not my go-to marker, and I doubt I'll use them much once I expand my Tombow selection enough to replace them, color-wise.
So given the #FFXIV crossover quest in FFV was what got me playing again, it feels fitting to come full-circle...
