I have a Mont Blanc fountain pen, which I want to use as my main pen but cannot due to the ink spreading and bleeding through cheap notebook paper. Thank you for the ink suggestion.
I should point out that I use a Lamy Safari, which has moderate ink flow. If your Mont Blanc is an exceptionally wet writer, and you don't want to get the nib adjusted, you might want to try Noodler's X Feather, which is a version of Noodler's Black with even lower feathering (at the cost of longer drying time). But I suspect the drying time could be annoying, because Noodler's Black is already somewhat slow drying.
