There really is no reason to. There are some subtleties with heavy gauge Sub ohm. But I can push similar clouds as many subohms with parallel 32g at 1.3.
What's baffling is 1.8ohm of 24g. That wire is massive you need a lot of power to heat it quickly. 80-100w I guess would do it.
Its a combination of the mass of wire and power it takes to heat it to temp efficiently. With the thick wire and all those wraps its a lot of metal to heat up.
Currently I use 1.3 ohm of 28g single coil at 30w and I can blow a respectable cloud with only a 2 second vape.
40-45 watts, 3 second hits with my istick50 it heats up relatively quickly honestly.
