Black ink. Sigh. It's time for me to get a new bottle of black ink. I've narrowed it down to these four: Skrip Black Monteverde Midnight Diamine Onyx Namiki Pilot Which of the above is blackest, laying down a smooth dense line that doesn't feather AND which plays well with many different pens? (Unless there's a MV ink I haven't thought of). Already owned: JH Perle Noire Pelikan Quink Levenger Raven (horribly feathery, apropos I guess) Waterman MV Black Ash Vintage MB that I hesitate to use too often Thanks for your help!
