So I have a TWSBI 580 1.1 stub, and I've discovered that I don't like writing with stub nibs as much as I thought I would. I like the feel and heft of the pen though, and want to swap the nib out for a fine or medium. Does anyone have a TWSBI with a medium nib? I have a Classic with a fine nib, and would like to know if their medium is a small step up (like the Pilot Metro medium nib) or extremely broad, which I would find too bulky for everyday writing.
