Very nice! I ended up with a Me/Me/and I (mezcal/Meletti/and Italicus) - I find that Meletti is very similar to Montenegro and is a bit less expensive, so I tried it. Rich and darkly sweet, and a nice note of smoke that really combines well with the amaro. The Italicus adds a bit of brightness, and makes a fleeting appearance as the leading flavor note after the initial sip but yields well before the finish.
