Thanks for the photos and the comments. I guess what I really want is something like the 9556 that I have but finer. Mine writes nicely. It's smooth yet providing some tactile feel, nice fine line variation, and has smooth flow. I'm not so interested in the non-9XXX Estie nibs as they're not Iridium tipped.
I also have a Waterman, but it's the Kultur with an F nib. It's still a little too thick for my taste. Even my Pelikan M150 with EF nib is thicker than my Estie 9556 fine nib. This is even more so with my Lamy 2000 EF. It's hard to get a standard on Western F/EF nibs and I'm just really glad that Esties may be comparable to Asian nibs which really give finer lines given the 20+ strokes in the characters they have to write with.

I have a couple 15XX nibs (more common versions of the 95XX nibs) and I can't write with them worth a crud. I can however use a Hero F nib pretty good and a Waterman Phileas F nib.
The 15XX nibs I have flow just fine but the lines are skinny as compared to the Hero F nib. Hope this helps a little and I have attached pics of said Hero nib, a Esterbrook 1550 (which will draw blood if your not careful) and a 9128 EF (which I can use somewhat).
I guess in short, I can use the Asian F nib easier than the Esterbrook F/EF nibs but all of them flow very well.
