I'm with you Bo Bo, I mean, I think I understand what you mean.
I started writing with a Pelikan 120 in the 60s, and true, I was a kid then, but compared to available pens, the 120 was already quite a big pen at the time. Particularly other pens were thinner, I did try some of them. The 120 was quite a fat pen then.
To tell you the truth though I learned to write uncapped, and never learned to post (nothing to do with religion in my case... )
Still today I use the 120 unposted and does not bother me a bit.
Pens were not just smaller in width they were especially shorter in length vs today.
Consider all the vintage pens, some of them were tiny! Think of some of the Conway Stewarts...
I even still use an Omas 1930 (555/f considered a lady's pen, unposted...).
(The new 120 has solved that for me, it's somewhat longer and great to hold even unposted - but I'm not giving away my vintage 120s... or 140s for that matter ).
The m200s are daily writers for me, unposted, and they work just fine.
The 101N is a wonderful pen, new and old, I use it uncapped and just love it.
I have grown to like much bigger pens, and my hand has learned to adapt. The m600 is my average best size pen, but I am not alarmed by larger pens.
Perhaps I will pass the M1000 and MB149, but never say never.
You are right also in saying that large cheap pens can be found (chinese/indian) although it is also true that traditional pen companies usually ask for a rising price as the model gets bigger... (this topic has been discussed before, I will not go further, except mention that I believe - my opinion - that the growing size of pens has to do with the "bigger is better" idea, which of course is not always true).
Back to the 101N it's a lovely pen, and I think Pelikan has merit in believing in tradition and proposing such nice modern replicas (as they have done with the 120).
The Lizard is still under my radar...
