I don't see the point in splitting the syrup base. What are we going for here, looks or flavor?... Clonakilty the base. I made it with lemon and all grenadine. Not bad. Way more dark pink than the photo. Made it again with lime, cane syrup, and a dash of Peychaud's. Also not bad. Much more pale with a bolder expression of whiskey flavor. Your choice. At least the drink makes you think.

We double all ingredients except the soda. Fits snugly in our Collins glasses without too much ice to dilute things too quickly. Mind the ABV though.
