Gotta have a good set of tanks as I can't vape a single flavor that long. I have been running a dual coil mesh in the Origenny and I am liking it more and more every day. A real quality vape at 25W on 0.6Ω 26g with 200 mesh, just tilt and enjoy, but don't lay it over or put it in your pocket unless it's kept vertical. I found some stainless steel cheese head screws, 3mm x 35mm to fix my rigged up center post.
Like you say, these older tanks do really perform very well. But all the cool kids today want a sub ohm from Kanger, Aspire, Arctic, Herakles, Matrix, High Voltage, VCT Pro or a dozen more with way too many coils to be bought. All they ever complain about is dry hits and leaking juice. Ha Ha Ha
Quite the compiled review here:

Even vape shops are sending new vapers out with a Melo sub tank and an iStick 30W as there first device.
I will be picking up my Flash e-Vapor V3 tomorrow at the post office so it will be a daily driver along with the Nextgen if that works out.
Then I will be waiting for Hotcig to clone the 20ml
Flash e-Vapor dD. I'll also have to find a Congestus or Vapor Giant to put it on!
Should look something like this on the dual 26650 Congestus, with the KBox as a size reference .
