No, I've only played with dual coil setups all around the 0.2 to 0.5 range. How many ohms is that setup running at?
You can try a quadcoil made up of four 3 ohm 34 gauge coils; that's 0.75 ohms;
so you'd have 4 coils spread out over the deck getting airflow from the sides, each coil using about 5 watts, for a total of 20 watts but since it's spead out over the deck, you don't have all your heat concentrated in one spot, so you should get a cooler vape.
I have not tried it myself though. I'm still using single coils so far.
