You know, I just did stop myself and consider that. I've been searching high and low and racking my brain to get one of these cool mech side by sides to be regulated.... then thought hey wait- maybe I dont even need that and just THINK I do.I want a consistent vape and battery life, but would I even notice the difference if I build the right coil? Not sure, never really used a mechanical...scratching headI'd almost consider that, with kayfun Nano's, if I even slightly believed that you could screw that on to a Kato... Then again, I am happy with my 1.2-4ish KFL's in mech mode with 18650's.
