Heads up on the NET juices, I recently purchased a number of their flavors after hearing good things from a fellow member at another forum...he did warn me about accelerated fouling of coils and wicking material, I couldn't get thru one full tank with any of the 5 flavors I tried before that all started to taste burnt and pretty horrible.
This is generally true. Most NETs will trash your coils in a quick hurry. There are exceptions though (as with most HHV NETs). It is also true there are some non-tobacco e-liquids also capable of trashing coils quickly. I use drippers for the gunkers...easy to clean and small capacities so I don't have to wait till the end of a tank.
