Hmmm, a little research and I realize that I've been making this "wrong" with Campari. I'll have to try it with Aperol. I believe Nonino is a milder amaro than Ramazzotti, so I'd expect a more delicate, less bold, drink. I also got the name wrong, so I'm going to continue to call the Campari version Paper Airplane, rather than Paper Plane. I also prefer it on the rocks. It mellows nicely as you drink it, changing in a pleasant way (unlike most other drinks which become a watery mess).
The Paper Airplane (the version with Campari) is a Toby Maloney tweak of Sam Ross's Paper Plane (with Aperol).
