Thanks for the thorough review @AJS, I guess you were inspired!
Were you using the atty in Power or TC mode?
From my experience with commercial on-demand convection vapes as well as building my custom ones (including the Project variants etc) I tend to prefer the inertia that a large mass heater provides. That's exemplified by the Zion (at least the two I have, since the latter versions seem to have more mixed feedback) where the train metaphor was not chosen without any reason: you need to get it rolling, and once it does, it's like a freight train!
When the coil(s) is/are small, I find that temperature control is a must. For instance I find my MVT quite finicky to use as the coil is small and heats up and cools down very fast. Same way I found the Project barely usable in Power mode unless you use a very low value (ex: 20W) hence why I use all 3 variants exclusively in TC mode.
With a light mass heater your heat curve ends like a saw tooth very quickly with ups and downs. When you add mass, it's like if you were applying a low pass filter to the signal: it smoothes fast changes out. Of course at the cost of more inertia and less instant "on-demand action". You need to wait more to pre-heat before drawing etc.
Plus there's the higher surface area argument. As well as the fact that with more mass/surface (i.e either using a mesh or smaller gauge wire) you don't need to get the metal glowing. That's really a plus as there are valid concerns around oxidation and metal fatigue.
