I have the smok Mag Grip (18650 battery), the vaporesso cascade tank and vaporesso .5 ohm coil which i love. I vape very cool, on watts the lowest recommended which is 25 it's even a bit high for me. I was wondering about using TC, the coils are SS316L, so i set it to steel, 25Watts, but then it asks for another number which i believe is the "TCR" it is adjustable from 0.00010 to 0.00300. I have no idea what to set the last number at. The ceramic coils are great, low power, great flavor and they last a long time, just wondering if I can get better results in TC vs just Watts. Thanks!
