I've been recommending the Naturevape Pro Mini because its so damn easy to wick with cotton, and the flavour is unbelievable. The flavour is a biggie for me. That and the throat hit. If its not hitting hard, its not worth it. Thats where nicotine levels play a big role. Anything below 18mg and the throat hit doesn't quite do it for me. Some 11mg flavours are ok though, namely menthols. If you go for the NV tank, pick up some Ice mint from him too. Lovely stuff. If I have a crap flavour (USA mix), I usually mix it with some Ice mint to kill it. Works well.
