I'm not a font person, what with all the intricate details concerning the look of text. But I do like certain styles and more importantly the spacing between lines.
I didn't know by changing fonts, you could change the spacing in Logos4. At least in my own software, the spacing remains almost the same. Personally I like serif type fonts, and so Abyssinica provided a nice font but more importantly a more spread-out line spacing.
Oddly this also (hope George isn't reading this) adjusts the interlinear lines and even some of the non-western text spacing (eg syriac, hebrew, etc) though not sure why on the latter.
You have to watch the choices though ... my Abyssinica cleaned up my DSS Bible of all those pesky little symbols that weren't correct anyway under 'Default' font.
