I normally stay at around 1ohm in my dual coils and yeah, they produce thicker vapor, feels kind of creamy when
vaping VG based e
juice. I'm just starting to experiment with dual coils right now, I have a Trident set at dual micros at 1ohm, and an aqua clone at .85ohm.
To me, any higher that 1 and its too slow to heat up and boring, and anything under .8 is just to darn hot, even with wide open airflow
