I'm looking for a font that renders well on a spiral-shaped path (I'm not talking multiple loops around the center, of course; perhaps a third of a revolution, not very steep).
Try stuff made only of straight lines, like Brothers.
I think a lot of it all depends upon size and spacing. I've found some spacing allow the eye to fill in the gaps without having a rickety baseline.
Maybe something "top-heavy"?http://new.myfonts.com/fonts/bomparte/so-ho-nights/http://new.myfonts.com/fonts/3ip/bonsai/http://new.myfonts.com/fonts/t26/girlfriend/
