Don't know what paper you are using, but that is in between the two views I've seen so far. Thanks for delaying the work to let us see.
I think as I said this will be nib and paper sensitive.
Semi-flex in different widths, will be different that the somewhat dryer 'true' regular flex and more than likely even dryer semi-nails.....tine spread is one thing.
Adjusting a less flexible pen to write wetter another.
Someone else will have to test that.
I hope a few test it with wetter or wider or narrow nibs. I really don't want to ink too many pens for this. A semi-flex M and a regular flex M....can be dug up by me.
I can see using three or papers, in that can make a great difference as Sandy1, proves all the time.
Just a photograph, in I don't have hours to learn how to finally use my scanner that has sat in it's dust since new. Procrastination is my main hobby.
German vintage '50-70 semi-flex stubs and those in oblique give the real thing in On Demand line variation. Modern Oblique is a waste of money for a shadow of line variation. Being too lazy to Hunt for affordable vintage oblique pens, lets you 'hunt' for line variation instead of having it.
