A lot of "gimmick" pipe designs have come and gone, often either because they provided little, if any of the superior effects they were intended to provide, because the inconvenience they were meant to resolve was too minor for many to be troubled about, or, quite simply, they resulted in a clunky aesthetic and/or cumbersome feel in hand. Such are the very reasons that they're now generally thought of, dismissed as it were, as "gimmicks".
The reverse-Calabash doesn't seem to have any of those problems, however, which no doubt explains why, despite being a pretty recent innovation, the list of skilled artisans who've made them is now approaching the length of my arm. Those who've tried them have been consistent in their reports; it works. The unconventional engineering results in a significantly cooler, drier, mellower smoke, period. On top of that, it's adaptable, allowing for designs ranging from a antiquarian-looking Oom-Paul with the cooling chamber tucked into its base, to creatively organic freehands, to playfully fat-shanked reinterpretations of the classics - like this Radice.
