I've made so many variations and substitutes on this and they all came out really good. Rye and funky rum create a solid base. Try subbing unsweetened cranberry for the grapefruit and a slightly less dark rum. Delish!
I upped the rye to 1.75 oz. very good.
I used only a half oz of simple syrup, grand mariner instead of contreau and a bit extra grapefruit and a little less lemon. Pretty great!
