In reply to A faithful sans version of Garamond?:
Look right there in the first word (of the GF link). Please don't tell me "rum" is balanced. In your (arguably too low-res) print sample, look at "estiró" (at the beginning of the fourth paragraph).
I wonder, how many hours did Gatti spend on spacing? Just for reference, I'm currently finishing a spacing commissions: limited character set, two weights (with very close Italics) = about 15 hours. Zero automation BTW.
