I used the medium style for two hours at pretty small font-size (8pt) on a light background. And i must say i kind of liked it so far. The greater line height and letter spacing looks good on smaller sizes. On greater font-sizes the letters getting to much "personality" and the font start to feel out of bounds. It is as easy to read as my preferred font but in smaller sizes. Which is appreciated. Not sure if really want to switch, though.
