I never used a coil smaller than 2mm diameter, even in the old kayfun Mini 2.1 and that was a 14mm rta.Damn... And I just wrapped this... Vapes well at your power reqs.

For dual, you'd need a 1.5-2mm max inner diameter with really fancy wire. Coil placement is going to be critical at that size though
Are you talking about those Dragon nano coils RipDripper used to wrap with cotton back in the day?
