Still looking for the vape experience that really satisfies the hubby. Right now he has a Toptank mini built at 1.5 with the airflow turned waaaaaay down and uses a restricted lung hit. I would love to get him a nautilus but I'm not really interested in buying tanks that require premade coils. I guess first off, is there a good rba option for the nautilus? Or, which RTAs have that similar hit style? Any other suggestions for restricted lung hitters would be greatly appreciated too. He's definitely a tootle puffer, and likes to stay under 20w.
