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

If you write small, go with anEF
For the normal writer,Fis the most popular
If you tend to lean on a bigger font,Mwill be perfect
Bis for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
Stubnibs are italic in writing style (have a special card or invitation to write?)
