I have something in works with the Gn0me heater,but have yet to buy an e-nail to see if it is going to work in reality .I dont see t any reason why this wont work with 7thfloor concept either ,maybe will have to bump the temps a bit,but e-nail coils from what i see can get quite hot. Also as cool as that concept it is ,providing more accuracy ,i think it robs some of the all glass romantics of the device,adding a heated metal coil near the air intake. Someone commented that this vape made his bubbler smell unpleasant. After playing a while with that type of heaters i think it is essential for its hygiene to remove it prior end of inhalation. So you can avoid blowback and rising vapor from the heater bowl to come in contact and recondense on the heater,which results in the taste you are describing.
