That's why so many of us migrate to VV/VW, so we don't have to be so picky on coils. Just adjust the voltage/wattage to taste.
I have (among too many other things!) a stash of fixed voltage autos. There are times I want to vape and need both hands for what I'm doing. 1.8 ohms does work well at those voltages, or LR cartos. Even the Vivi Nano works well on them.
