I think this modernized version is much better than the equal parts original - I would even increase the cognac slightly to 2.25 oz / 67.5 ml - but it's still an intensely minty cocktail that bares for me an unfortunate association with toothpaste. My favorite version dials the Creme de Menthe way down - 2 oz / 60 ml cognac with 0.25 oz / 7.5 ml creme de menthe - for more of a minty cognac Old Fashioned feel.
