The Nautilus coils are only available in 1.6 and 1.8 ohms.
The resistance (ohms) has nothing to do with the draw/airflow.
I direct lung hit a Nautilus coil, at 1.8 ohms, all day.
Of course, it's in a Kabuki, so that's why I can open the airflow enough to lung hit it.
Of course, with the Kabuki, the v1.5 and the P3 versions accept the Triton coils, which I believe are subohm, and also have much wider airflow holes in their pins.
The flavor/performance isn't as good as the Nautilus coil, because the Kabuki was designed around the Nautilus coil specifically...but flavor/performance can be subjective, so your mileage may vary!
