you know this topic is been tossed around for a long time, its the low resistant guys vs the high resistant guys. i am just a low resistant kind of guy. i have always felt that a thicker wire produces a better flavor, and that a lower resistant coil produces a thicker vape. some people like to vape a certain wattage, my perferd wattage is between 13 to 17 watts, thats just me, so now its a matter of whether this wattage is going to be a high resistance, high wattage or a low resistance high wattage. well i just prefer the low resistance, high wattage much better. now with a mechanical mod, with these wattages, my batterys will out last my batterys in my provari any day. i can vape a 0.8 ohm coil for like 10 hrs in my mechanical mod, in my provari my baterys will only last 4 hrs with a 1.2ohm coil at 4 volts. then you will say that the vape in the mechanical mod will suffer as the bats are depleting, not really true, its hard to really feel the drainage from 17 watts to 14 or 13, its very slow and you really dont feel it that much. so for me this is not an issue, and with quality hi drain batterys this is well within the limitatins of the actual batterys. so in short lol, this is why i perfer low resistant coils, they are just hands down better. now for ceramic, i dont know yet, for i havent tried all of the possibilities yet. so far i must say that the 30g 1.2 ohm coil is out performing the 32g 1.8 ohm coil that i was running before.
