I really like the Evo 2ml tank and the coils that came with my NX75 kit but I prefer to have a bit more juice capacity. I enjoy the flavor I get off the EVO coils in this tank and the only negative is that it's little difficult to screw off the top when I want to fill it because I feel it's just a tiny area around the top cap to get good leverage on with my big hands. That being said I see they have the extender for the Evo but I'm worried about the possibility of the extender chimney becoming a hassle if it screws off the coil head when trying to fill or top off the tank. I also haven't seen any SS coils for TC yet that are designed with the larger wicking holes that go to the bottom of the tank so you aren't left with juice like when you try to use a regular Triton coil in the tank. So I got to looking at the Cleito because the tank already holds more liquid without having to mess around with the extender piece. There are also SS Cleito coil heads for TC which is a big plus for me. I'd guess I would like to get everyone's thoughts and opinions on the Cleito and the Evo with the extension. I don't care to vape at higher watts so I am not even considering the Cleito 120. Also to add to that question, is the NX100 mod ever going to be more readily available from any US retailers. I really like using 26650 mods and also that it can accommodate bigger diameter tanks.
