Thanks Kevin for starting this thread! I'm really excited that Luca over at Neatpipes has begun manufacturing the reverse calabash design in its new line of Chubby, called the AeroBilliard. I'm sorely tempted to pick one up. I understand that Luca began the project after visiting Rolando Negoita.
Last year I commissioned a reverse calabash design from Rolando Negoita called the Conducta. And I must say its my favorite pipe. I even had Rolando stamp my initials on the pipe so I could never sell it. If you tried the Calabash, then you'll understand these reverse designs. The chamber provides for a much more flavorful and nuanced smoke. Here's some snaps of my Conducta. Easy to clean too, as you can loose your pinky in the shank!
Mark Irwin's blog on Neat Pipes has a brilliant writeup on the history of the reverse calabash design. Really exciting to see this concept take off.
