1. Any battery, but true 3.7V (or above) preferred for best results. Suggest an
eGo VV battery or
Riva or, if you prefer a mod, the
Lava Tube for an inexpensive VV.
2. A Vision clearomizer (
here,
here, or the small one
here)
3. Optionally (but recommended), perform
this mod on the Vision(s) to completely open it up and allow it to produce massive amounts of vapor with better flavour and TH.
You now have a high capacity, long-lasting clearomizer setup. From my point of view, this is just about the best flavour, vapor and throat hit you're going to get through Canadian vendors, and from my experience, on par with anything, including dripping.
Note however that you should avoid juices with citric acid (some citrus fruit flavours), malic acid (sour flavours) or cinnamon flavours to avoid cracking the tube. If and when the Vision 3s cross our borders, you won't have these problems.
