Excellent mix, should be a tiki classic. Smith & Cross and Appleton Estate 8-year-old Reserve. Didn't have DeGroff's Pimento Aromatic Bitters so I used my homemade, unsweetened pimento dram, which doesn't have the bittering agents of a bitters but has lotsa pimento + other spices. A good dash each of St. Elizabeth and Angostura would also probably work in a pinch.
