Yep, have the subtank mini. Because the standard coils are relative expensive, i decided to build my own coils. I prefer being in the sub range from 0.4 to 1 ohms, firing it between 20 and 30 watts. I notice comparing to the lemo2 that the subtank mini generates hotter vape then the lemo.
In the end i decide my wattage by getting dry hits or not and that depends on how well i build my coils and wick and on the juice whether it's thick or not.
