> A small diameter like .5mm is silky smooth

When I was in high school, I bought a .9mm mechanical pencil, and it was glorious for standardized tests. Filling in circles was just a quick spiral inward, and the forms with rectangles were even easier — just a swipe across. I still have the thing, even though I haven't taken a multiple choice test in over a decade.
