Copying this from a PM I just sent:
I just vaped through a tank each of v2 Diver in BB and v2 Diver in Scuba. Same 50/50 juice, same generic coil wrapped around 2mm silica @ 1.3-1.4 ohms - basically what K sends out as his pre-builts. The ONLY difference was that I removed a single thread of silica from the strand which was left long. So the strand that was cut to the ceramic was full thickness, the one that was left long and trimmed at the exterior juice slots had one strand of silica removed.
I did not remove the tanks for any reason from the BB or Paps Lux, I replaced the battery in the Lux from the switch end.
Zero gurgling, flooding or leaking. The Paps top cap is bone dry, not even condensation on it. The BB 510 base has a tiny bit of condensation on it, much less than a drop. There's some juice on the back of the tank, a thin film adding up to maybe a drop of juice. I get that in the BB with any build, though.
I had no dry hits in the BB, but I did get 2 or 3 points in the Scuba when I got dry-ish hits, after really chain vaping it though, and they went away after 1 or 2 drags every time.
I did not get the dry hits in the BB at all. it worked flawlessly, every single draw from start to finish was perfect. The first draw after leaving it sitting for a full day on my coffee table was a bit overjuiced, but not a gurgle, just a a slightly "wet" draw, but producing full vapor and flavor. The second draw was right back to normal.
I really really hate to sound like an Atmistique shill, but this is close to a perfect vape, as perfect as my Spheroids.
So much so, that I am in the process of selling a number of other devices, and replacing them with at least 3 more v2 Divers and the new 22mm Spheroid, the Heron.
You stick to what works for you.
