Well, here's the thing... I don't do either -- don't use "blister-pack" coils... nor 'blow serious clouds' -- so very OBVIOUSLY I'm not a cloud chaser. And I've never gotten CLOSE to 15w in going-on-2-yrs of vaping.
A lot of you folks need to chill with the categorizing. I make my own coils ALWAYS; you couldn't pay me to use packaged coils, nor sub-ohm tanks, and anything I exhale is a mere side effect, not the reason for vaping. The reason for vaping is to NOT SMOKE; cigarettes don't produce much either, except in the stink department. The reason for building coils is to NOT GO BROKE BUYING THEM, and not spend half my life waiting on the sluggard mailman to bring me something I REQUIRE for vaping. That last is also part of the reason I DIY my ejuice.
