In another thread you asked about higher wattage and lower resistance. Low resistance does not necessarily require higher wattage, its all about coil mass. If you are used to running 22AWG dual coils at lets say .25ohms and 75W then building lower resistance will require less wire, thus reducing your coil mass and will also result in using less wattage for optimal use.
If you want to increase your cloud production then its partly in the build and mostly in lung capacity.
If you really want to increase the mass of your coil for a lower resistance build that requires more wattage then you need to build heavier and more complex coils. Claptons and Twisted wires are good place to start, but then there's fused claptons, alien wire, zippers, and so on.
