All these lovely VPs are making me itch for another in F or EF
I guess that you might find a japanese EF useful for scetching, but I wouldn´t personally want one as a wriing instrument. It is just too fine for me.
The writing sample in the photo is on a horrible notepad, which makes the line much wider than on paper of a reasonable quality.
The same pen on Rhodia is extremely thin for my taste (I usually writw with a fine or F/M nib). That being said, I also find my fine nibbed Visconti HS to be a bit too narrow. That should give you an idea of my preferences
I intentionally chose a nib on the fine side, because I want this one to be practical and lay a dry line for quick notes.
