I tend to remove hinting from fonts, because it can cause havoc with eink if the font has been hand-hinted for LCD screens. If you ever come across a font that looks plain bad on eink (I'm talking uneven widths, especially on characters like 'e' or 'c'), chances are it's the hinting.
Well, I assume Amazon put some work into their hinting to be e-ink optimized so I'd like to keep it if possible, but regardless, shouldn't that data already be included in that stock 300kb? Or am I misunderstanding how the Fontforge hinting option works (the help tip says that new data isn't created and just uses what's already there, and I've disabled auto-generation of hints in the options to ensure it doesn't regenerate anything)?

Edit: And in this case, disabling hinting doesn't have much of an effect on file size; it's still over 1 or 2MB.
