Quick update: a change of ink did it!
Oct. 27th, 2022 05:12 pmI cleaned "the pen I hate" and put the ink that used to be in my favorite pen into it… and it writes so much easier than it ever did with the first ink I put in it! So will definitely get rid of that ink in my favorite pen. My order (out for delivery to arrive today) will have 11 new inks to try (8 free samples, and 3 bottles), plus the means to try 3 inks I already bought in containers that don't work for filling my pen from. One of the new inks will go in my favorite pen. My new pen will probably get my favorite purple, since it's an ink I know works and the pen is a stub nib. (I only have one more known good ink… but it's already in a stub-nibbed pen, so would be less useful to have it in the new pen, too.)
