Red ink recs?

[swan_tower]

Fountain pen users! Please speak to me of your favorite red inks. I have a few Pilot samples, but they're all more in a magenta or orange-red direction; none of them feel quite like a true, vivid red to me. It seems like a basic color I ought to have (especially when editing a novel, where I'm marking up a print manuscript), but rather than buying a bunch of samples, I'd like to hear what other people prefer.
