Stub nibs are not my favourite thing in the world. They are kind of scratchy if you don’t hold them in the right angle, and other nibs like my medium or broad’s are way smoother. But it looks so cool.
The way I use pens is that I have all the pens I own and enjoy inked up and I just cycle through them, and move over to the next one when my current one runs out of ink. And I have a system for cleaning them every other refill or something like that.
Most of them are in rotation because I love writing with them. The one exception is my TWSBI Eco with a Stub nib. I don’t hate writing with it, but I prefer every other pen in rotation over it. The main reason I keep it in rotation is how cool my writing looks with a sub nib compared to everything else I own.
