I have bought just only 3 days ago a Pelikan M400 (Oscar Braun shop, a very good transation -many thanks Pam!-) with a fine nib.
Well, the fine nib make a broad line in certain papers (not at all), I´m thinking to change fine nib for a medium, the question is: that problem will be worse with a medium or it depends more of the quality of paper than the nib?.

Jorge.
