I would suggest a nice springy regular flex '83-97 400 over a over a nice regular flex 200 that can be as good as a Pelikan 120 or a bit better as good as a '90's 400 springy regular flex....and a 200 over a modern 400 semi-nail.
The modern 400/600 nibs are a half a width wider, with a blobbier line, half a stiffness stiffer....semi-nail instead of regular flex.
A '83-97 400 is not expensive....a new 400 certainly is.
Luckily I live in Germany so watch German Ebay...being retired had to watch my money...and was getting lots of nice semi-vintage and vintage pens at affordable prices.
There for I missed the substandard nib on a 400...got one on my 605.
Of course if all you want in the world is butter smooth....a 400 will give you a nice fat butter smooth semi-nail.
It can be sent to a nib meister and made thinner and up to semi-flex. (reason I don't buy very pretty 600's. I want more than simple butter smooth. )
I'd just buy a 140 semi-flex as first choice..
Back in the '50's a medium small, long posting pen was In, in Germany...the 140, Kaweco Dia, and Geha's top of the line 760 was the same size as the 140.
These semi-flex pens post as long as a standard sized 200/400.
The single 1000 I tried was semi-flex....springy is vague...with the 200....is is only springy in the regular flex range. It does like vintage regular flex spread it's tines 3 X a light down stroke....when mashed.
A springy nib like a Falcon (often called soft) or a modern MB is springy...tines bend well but tine spread is only 2 X a light down stroke. That is it's own flex set...A bit more tine bend combined with a bit less tine spread...
Got one or two....got 26 semi-flexes, would not waste money on a pure "springy" nib....which has nothing to do with the spring of a very good regular flex nib.
