Tequila, Lillet, Campari, lime juice: decent, though pretty sure the Lillet got totally lost.
Tequila, Lillet, lime juice, orange Angostura bitters: “one note” — probably needed simple syrup.
Rum, Lillet, lime juice: better, and probably closer to the original cachaca; might start tweaking this base instead.
