Made with Kammer Kirsch and Leopold Bros Maraschino, with a pitted sour cherry I had just picked in the yard. Very good stuff. I don't mind the dryness but I'd add at least a splash of simple next time for a slight bit of balance. Lovers of cherry flavors will like this.
EDIT: Couple months later made this as a frozen drink after getting a Vitamix. Added a good bit of simple (didn't measure) and it was good, but still needed additional sugar more than the regular cocktail needed any sugar. Either way, having fruit juice and simple means it blends very well into a frozen cocktail.
