I wanted to try this, but I don't have Jaeger. So I subbed 1 part Branca Menta, 1 part Ramazzotti, and 1/2 part anisette. So 5 different amaro/liqueurs, plus the bitters. This version was quite minty (Branca Menta), with the cola notes from Ramazzotti and the Montenegro working well. The anise was faintly in the background (probably should dial up the anisette to better reflect Jaeger), and the pimento bitters were lost among all the other flavors. A nice, enjoyable drink as I made it.
