Would it make sense to have a supply of tank carto's of differing resistance when using a DAV?
As I understand it, the only dual coil cartomizers are 1.5ohm (2, 3.0ohm coils wired in parallel. I assume this is done to increase wattage from lower resistance, hence more heat...but I digress).
I'm thinking I can achieve the same "heat" by "dialing-a-volt" so to speak.
If I set the DAV to 4.7v with a 3.0ohm carto, that will output 7.36w. If I set the DAV to 3.3v using a 1.5ohm carto, that will output 7.26w...close enough to the same "heat" I would think.
So if I can get the same (or very similar) power output using a single carto type, is there a reason I should have something other than a 1.5ohm DC carto?
