I've got a couple of Rangas and a very tightly-tined nib on a TWSBI that I like to fill with wow greens. I am searching for wet, lubricating inks that will help these pens flow.
I like saturated colors, maybe some shade and sheen, and even some water resistance.
Noodler's Eel Gruene has been my go to, but I'm not nuts about the color. (I prefer bright greens, nothing Army shaded with grays and blacks.)
I've tried Diamine Woodland, KWZ Emerald. What else does the world offer?
Unlike Veruca Salt, whose image I'm not allowed to post, I won't scream if I don't get it, but I will keep looking!
