Reo Grand, with the RM2 RBA. Micro coil and cotton wicks. It's so simple, I even managed to teach my wife to do it. The ceramic base of the RM2 really does wonders for the moisture of the vape. Very flavorful, not dry in the least, and when the wick needs changing it's quicker than changing out a Vivi Nova head (almost), not that I use Vivi Novas anymore.
I don't think I'll all day carry anything else.
