[TysonMN]

Consider the phrase specific floating office, which includes ligatures for fi, fl, and ffi.

The spacing after all these ligatures looks good for light weights. The spacing after the ligatures for fi and fl also looks good for heavy weights. However, the spacing after the ligature for ffi gets increasingly worse (by being too big) as the weight increases.
