Biber did you start with Japanese pens?
If so, your Mark 2 Eyeball is so calibrated and all western pens will seem wide marked to you.
Aurora is the thinnest European nib, close to Japanese....perhaps close to the Fat Japanese Sailor nib. Pilot is the Skinny one...so buy Pilot.
My eye is a Mark 1 Eyeball, calibrated to American widths of B&W TV...so Japanese are miss-marked one size too narrow....Gee their B is only an M...and sometimes a skinny M at that!!!!
......and in the '80-90's according to a chart I have, both Parker and Sheaffer was fatter than Pelikan.
Pelikan also had then a thinner nib set just for the 800.
On that chart Waterman was thinnest (it came out later Waterman also had two nib widths....one exactly matching Pelikan..............but in All Cases, the Pelikan EF was thinner than any of the others. Even the Waterman................there use to be flame wars here with Waterman users claiming skinnier....to Pelikans change a nib answer.....then it came out Waterman had a fat 'Pelikan' wide nib set too. That is when the flame war died.
There was of course no Waterman user saying my Waterman is Pelikan Fat........when remembering Pelikan then was thinner than Parker and Sheaffer............which some good poster said is no longer true; but was once.
Back then at the time of the chart, Japanese pens were fringe and not in the mainstream.
They became popular by planning ahead, selling a very good nibbed pen under cost to get folks hooked on skinnier than marked nibs.
So you could look at semi-vintage regular flex from that Chart's era, which are thinner than modern....I'd stay away from semi-flex....in you might have a Heavy Hand, and then they would write wider, due to ease of tine bend.
You can either buy Pilot pens, or send your 'fat' 200's nib off to a nibmeister to be made Japanese skinny. Or look for semi-vintage EEF in 200 or 400....the 400's of that time were 200's skinny.
Some day if you ever get into shading inks M is a good nib...thought F will do too, in a 200. Right now with extra skinny nibs, you are condemned to using vivid supersaturated inks....EF even "Pelikan" fat EF is not a nib for shading inks....IMO.
