I tend to think of these equal-parts sours as a category, although I’m not aware of a generic term for the group. I suppose they’re all descended from the venerable Last Word. Paper Plane and variants have been going strong for 15 years now. Naked & Famous seems to be on rise lately.
A lesser known example that I also like is Monte Cassini - rye, yellow chartreuse, Benedictine, and lemon juice.
A local joint crafted a more, shall we say, strident entry they called an Industry Sour - green chartreuse, fernet branca, turbo, and lime juice. The color is off-putting, but it has a big big flavor. Unlike some others, this one wants a lot of shaking.
