while some of the theory is sound some of it makes no
sense, how can a sub 1 ohm coil running at 4 volts (on a mech) use less power/voltage then a 2 ohm coil running at 4 v ?
lol not sure how(in your example) 8 to 10 watts is more voltage the 15 watts.
i think it has more to do with the setup if you learn to fine tune what you are using it should all work about the same. after a certain point how much bigger of a cloud do you need? by the time i get to wrk 20 min away my car looks like someone lit a smokebomb.
if there is no trying different ways (loose coil, tight coil, oxy, unoxy, straw, solid wicks etc) there is no real way of knowing if it can be done with a particular wire or wick. just doing things one way with so so results and moving on isnt enough to say the last way wasnt good enough, just it didnt produce the results i was looking for in that setup.

two different cobras running around 1.8 ohms with 32g on 500 unoxy and i stay right around 4-4.2v right around 10 watts or less. now add some airflow to that and you will fog out the room.
