Hard part is getting the per coil power needed when using Ready wires. Lowest I have found, long enough to fit decent are 1.8ohm or a .9ohm build. This equates to about 8 watts per coil running on an 18650
Jumping up to 2.5ohm yielding a 1.25 with a 12 watt kick drops lower to 6 watts per coil.
This gets frustrating knowing your so close and not quite where you need it to be.
I have started using 1.8ohm single coil builds with a cross pattern 2mm silica wick. this way I can run a kick and hit the coil with up to 12 watts. The uncoiled wick crossing over the coil acts as a flavor/feed wick and helps keep things good and wet.
On the single coil do you wrap your wire around both wicks or does the 2nd wick just lay on top of the coil?
