Unless you have money to burn, I couldn't recommend a Provari as a step-up from a KGO. Why not a Twist or a Vamo? The V3 is due out soon.I'm getting ready to order a ProVari, or an evic or something similar, VV/VW for sure, so I'll probably be switching to some type of cartomizer tank setup..
It's hard out here for a pimp.
Oh, and I established that the horrible taste I experienced when trying Alchemist's Cupboard's Work, Rest and Play juice wasn't me burning the wick. It was the rancid taste of the juice. Avoid.
It appears as though a decent chocolate flavoured juice is an elusive beast.
