I have a set of the PR big-time blues: Lake Placid, American, DC Supershow, and DC Electric. Glad I have them, and will search for a second set. When I started using fountain pens again, about fifteen years ago, everyone said "use Noodlers". I never found a Tardiff blue that I liked...too much shading off into teal, and the one nicely purplish ink -- Blue Eel -- would not dry. PR had just the sort of purplish blue I wanted, so they became one of my standard saturated inks.

Sad news.
