Very minor point, but the artist that provided the inspiration for the name is Tricky, not Tricky Kid. Going to make this cocktail tonight, but probably won't end up naked and famous myself.
I agree with a number of others here - reducing the Suze a tad makes the drink more balanced. So the ration became 1 gin/ 1 Cocchi Americano/ .75 Suze. I had no grapefruit twist but a dash of grapefruit bitters spread over 4 cocktails worked well.
