First fountain pen of my life. Parker Vector with "Medium" nib. I've already had it for two weeks, and although this was only meant to try out fountain pens, I think I'll keep it, since the nib is a great compromise between being smooth while not being fussy with office paper. Already chewed through a cartridge. Only bad thing with the pen is that the grip is a little meh – my fingers don't really like it.

My next will probably be a Lamy (mostly Safari). Any recommendations for the nib size so it fits my criteria?
