The Aperol lightens it up compared to the standard Negroni, but the carpano + Averna retain the body and fullness of flavour. A nice freshness of the orange twist highlighting the citrus in the amaro. An excellent Negroni riff.
Used Oregon Spirit gin and replaced the Aperol with Contratto Bitter red liqueur ("Campari Lite"). Still kinda sweet but more bitter flavors than Aperol would provide. Per D. Kavrakov I gave it a dash of Bitter Truth Aromatic Bitters, which complemented the Averna nicely. The Averna makes it heavier and richer and more complex than a conventional Campari-based Negroni so I garnished with lemon zest instead of orange for contrast. Very good Negroni variant.
I don't have Antica, so I figured I'd try Punt E Mes as a vaguely strong vermouth..it's good, but I wonder if punt e mes simply isn't in the same class as antica here. It's just quite a muted negroni.
