Tried this tonight after having put it on wish list last year when it was "Cocktail of the Day". I debated using Difford's recipe or as suggested by others, Death & Co's. Settling on Difford's version, I agree with his comment below that this results in a spirit and vermouth-led cocktail rather than a citrusy sour cocktail likely to result were one to use the Death & Co recipe. While generally I'm not a huge rye fan, this is a delicious and well balanced drink. I should add as per his suggestion, I upped both the rye from 1.5 oz to 1.75 oz as I used 86 proof rye, and .25 oz of Jeffrey Morgenthaler's grenadine recipe.
