I usually make this with Evan Williams white label (Bottled in Bond). It is an inexpensive bourbon that I buy by the half US gallon and it is my go-to cocktail bourbon. The Maker's 46 definitely ups it by half a star. I think Maker's 46 cask strength would be even better, but you are then getting into Single Malt price range. Sam, himself called for a short, gentle shake, and I have been stirring recently.
