Just inked mine up with a blue-violet cart...and this pen is a very smooth writer. The pen was advertised as an M nib, and it does put down a fairly wet and heavy line...which I love and works well with my heavy-handed writing style.
It is a VERY nice writer for the money, though a bit large. I prefer the size of my X450, which doesn't write quite as smoothly.
