Since you're used to low ohms, rda's and perhaps lung hitting, why would you not look at something like the Orchid or the Erlkonigin clones vs the KFL ones? They have far deeper juice channels and excellent air flow in comparison.
Just curious about thought process, so I can perhaps make better recommendations the next time somebody asks.
Pop is not really a low ohm vaper Dust. He's been experimenting lately with subohm but he is primarily a 1.2ish ohm vaper.
