@pipster: I find I prefer NETs in top coil clearos when I use clearos. I think tobacco need the warmth, or, at least, it seems right for the tobacco flavors. I have ran NETs in Kanger T2s and Innokin iClears with satisfactory results. The iClears are fairly easy to dry burn as well and the flavor is good -- not Rebuildable Dripping Atomizer good, but good enough. T2's can be dry burned as well, just a bit less room to work with. I've run Organic #1 from Goodejuce, Analog, and several HHV liquids through both types, and yes there is gunking, but dry burns work.
The only bottom coil systems that have worked for me are the rebuildable tank design, such as the kayfun-style.
Others here have used top coil clearos with NETs, some more exclusively than others and have been happy with the results. Don't despair.
