+1 to that. I miss the pens of my youth:

They would sometimes fail, but I find they would leave just the right amount of ink on the paper while rolling smoothly on it.

The G2 also comes in a 0.5mm and 0.38mm version in all colors. As a lefty I prefer the 0.38, but I've found the ball fails more often than the 0.5 so I usually just put up with the occasional smear.
