As you can tell from my list I favor 14K Gold fine points. This is primarily because I like to write small. Why? It’s just the way I have always written. A fine or extra-fine point also lays down less ink on the page, which helps shorten the dry time, preventing potential smudging. As for why I prefer 14kt gold nibs - they are not only gorgeous to look at, they also feel smoother than writing with a steel nib.
I have also tried writing with a 1.1mm stub. However, my penmanship may not be worthy of such a nib. Plus, I can't write as small as I usually prefer. Yet, as a lefty, I can still get the line variations of a stub nib without skipping or scratching. So, it is possible - I just prefer finer nibs over a stub.
If you're looking for a specialty nib, like an Italic or oblique, I would suggest getting them ground and tuned for your specific writing posture. Since this would be nearly impossible to do online, I suggest attending a pen show and making an appointment with a nib meister (there are usually several at any given show) to have your nib customized to your handwriting style.
I learned this lesson the hard way when I purchased a Franklin-Christoph Model 02 pen from the DC Pen Show. I wanted an unusual nib and opted for the 14kt gold italic fine point. No fault to Franklin-Christoph, but I should have had it adjusted while I was there. The italic is unforgiving. You need to hold the pen at a specific angle. Otherwise, it will not deliver a smooth and consistent line.
