The Atlantis and the Kanger Subtank won't fire on the MVP2. The MVP only goes down to about 1 ohm (though some claim they've fired 0.8 ohm coils - however that really stresses the MVP) ETA - the Subtank's 1.2 ohm coils would be o.k. on the MVP, but I'd still opt for a better device if I went that route.
The iStick cannot subohm either. The Nautilus is a good tank (I have two full-sized and one mini, all of which are loaded with the BVC - bottom vertical coils.)
I've not seen one in person, but Aspire has a subohm battery (the CF) that's paired with the Atlantis. It's a pretty safe setup (but you should always be cognizant of limitations on your batteries -
http://www.e-cigarette-forum.com/forum/blogs/baditude/6740-18-baditudes-blogs.html has great info on battery safety, if you haven't come across this yet.)
Higher VG will lead to denser clouds. You'll have to be careful how much VG because it's much thicker and doesn't wick as well as PG.
I was in my B&M the other day and did get to take a hit off the Atlantis. It was pretty nice. I'm looking at that or a kanger subtank one of these days (probably sooner rather than later - shinyitus

)
iStick has some higher-wattage devices coming soon, and innokin will be releasing the MVP3.0 (30W) sometime next month (?)
I haven't even been vaping full-time for a year yet, and I'm stunned by all the changes I've seen just in the last 10 months. So many new and upcoming things out there. Do your research - make sure you understand the limitations of the goodies you get, and you'll be sure to find something that rocks your world
