I personally don't care for many of the modern FPs... generally, I find them too heavy to write with for long periods of time. I don't particularly care for the styling or feel of the Lamy Safari.

As far as point (nib) size... the line that gets laid down is going to vary somewhat depending on pen, ink, paper, etc. There's no set definition for what a "med" point is, for ex. For myself, I've found fine points to be best among modern. Vintages seem to be mostly mediums.
