    A quick no brainer guide in choosing nib sizes in an overly complicated fountain pen world:

    If you write small, go with an EF
    For the normal writer, F is the most popular
    If you tend to lean on a bigger font, M will be perfect
    B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
    Stub nibs are italic in writing style (have a special card or invitation to write?)
