What about an Artline felt-tip if it needs to be ink? You can get 0.2mm ones, and they are great. Or, if it doesn't have to be ink, my not a mechanical pencil? No bleeding, no ink-lag, and you can get nice dark 4B refills.
"Marriage is like a cage; one sees the birds outside desperate to get in, and those inside desperate to get out." -- Montaigne
