My favourite pen in the world is the
Papermate Flexgrip Ultra, medium, in blue. Yeah it's ballpoint, but the ink flows fairly smoothly, and I like the roughness of the line anyways. Part of what I like about writing is the tactile feel of pen on paper, and I don't get that as much with pens that move smoothly. Besides, those pens are more expensive, and I've never had a single pen survive long enough to run out of ink anyways. I have one nice pen (in this case, "nice pen" means one that cost more than 5 bucks) but never use it because i feel guilty biting on the cap.
The fact that I took the time to type out all the above? Another reason why I'm not cool.
