when writing, do you flex your wrist when writing? Stubs, obliques, italics all require concentrated writing to consider where is the sweet spot writing with any of these nibs. It takes practice to find where you are comfortable.

Also consider how you are writing. Many people will write with their hand. That is, every ascent or descent or downstroke of a letter, with or without a degree of pressure will result in a line variation, thicker or thinner.

After years of writing with a fountain pen I learned how to write with my entire arm, with no flexing of the wrist. It has become more natural to me and most important, never have wrist fatigue.

Try it, simply keep your arm slightly above the writing plane or desk top. You can still apply pressure anytime for more line variation. It will become an automatic method. By the way, with any stub, oblique, etc. you will have to write slightly larger letters as a smaller script may result in letters filling in with ink.

My nib of choice after all these years is a fine or medium stub and I always adjust letter size based on letter or card size or....how much I have to say. Saul, try to get to a pen show or a local dealer where you may have a chance to test drive various nibs.

Good luck and have fun finding your sweet spot.
