From what I can gather Conway Stewart Fine nibs are 0.7mm which makes them the same size as a Pelikan M and the Conway Stewart medium is 0.9mm which would put it between a Pelikan B and BB - does that sound right? ...of course you may or may not be a Pelikan users, so I am really asking if generally CS nibs are known to run large vs. other nibs? Does anyone have any info? ....I ask because I recently purchased a CS 58 with an EF nib which I was assuming would be way to small for me because I generally like a medium nib although I do have a Lamy 2000 F and a Montblanc 146 F which I regularly use when writing on standard office / copier paper. Thanks in advance! Bill
