Outside of cloud chasing on a rda running dual coils and 2mm airholes, there is very little to be gained IMO. I don't even need to try one of the clearomizers on the market today to know they are doing it wrong. The coils are stacked, and the airflow to the coil stacked on top is blocked. It's wasteful and fundamentally flawed design, and the OP is partially correct; it is a trendy marketing scam.
The thing is, everybody wants things "bigger, better, and right now." Of course your old clearomizer is obsolete... you need to throw it away right now and buy this new one with double the coils. Your so missing out, man.
