Here's a question, maybe observation, that I thought I would pose. One of my challenges in trying to get a nib set right is the fact that I'm left-handed. I'm careful not to bias my tuning, but I have found something along the way. If I run into a nice, delicate nib, I can find a little grab in the nib at some angles. Specifically, as a leftie, I am frequently "pushing" the nib across the page, rather than dragging it with my hand as I write. Has anyone noticed this? I have a couple of older pens with what I call fine, brittle nibs. They write beautifully, until I start pushing, and the nibs just want to hang on to the paper without budging.
