Don't fret smoking while you're looking for your sweet spot in vaping! Once you get everything 'ironed out', you'll switch to vaping and never look back. Alot of us still smoked while we were trying to figure out what device, with what juice delivery system, at what watts, and what mg nico strength, and what juice we liked best. You've definately got the device thing done once that Provari arrives.
I would suggest getting your juice delivery system in a 3.0 ohm whatever. If there happens to be a brick and mortar store near you, that might really help you with what juice, as you'd be able to sample lots of different flavors. Here's a link to vapersearch, so you can see some of the stores that are in your area.
