I've found that the cheap Chinese fountain pens, such as the Jinhao X450 and Century 100, and the Baoer 388 are decent pens, once you fine tune the nibs. However, those nibs don't have much "tooth" to them. I have a Goulet #6, made by JoWo, and it feels about the same. Is there a way to give a nib more "tooth", or friction? If not, can anyone recommend any decent steel nibs with the feedback I'm looking for, and a place to buy them? The Jinhao pens use standard #6 nibs. I think the Bauer 388 uses a standard #5? Is that correct?
