@TigoleBitties i also have all three. I use the Aether at a low temp sipper so I haven't run into any of the downsides of putting a quartz insulator between the coil and balls. IMO mixing metal and glass is a poor attempt at combining the best of both materials, which is zirconia. The hornet is worthwhile, although i don't really see it as that flexible if a ZX is also involved. At that point the only value in the Hornet is its conduction bowl, which is amazing btw. IMO thin walled conduction bowls are <3.
FWIW i've been into convection and flavor lately after amassing gear for conduction experiments lol. This past week I travelled with a ball vape and glass for the first time. I brought the ZX and Hornet. I didn't even have the Hornet hooked up some of the time. I also noticed that once I started using the z bowl in the middle shelf i basically stopped using the hornet. the Hornet conduction bowl is between the small and middle Z bowl shelves.
I am considering just travelling with the ZX, Calypso, and TM2 after my last trip.
