This is an interesting drink worthy of experimentation... The ginger liqueur measure is way too meager and seems to only truly surface in the aftertaste... I did use Cocchi di Torino, which is too heavy-handed here. Interestingly, increasing the whiskey (per the comments below) and reducing the overwhelming CdT resulted in a more balanced, but somehow less characterful cocktail. The extra whiskey seems to mute the flavors of the other two components... Will work on this...
