I went through EXACTLY the same process in terms of the TH. The vapor was fine as long as it was equivalent to an analog. I don't need a massive cloud, just what an analog would. The point being for me to replace analogs with this, that wouldn't work if it wasn't comparable in those ways. I have an eGo, DarkStar battery, and the Magma from Volcano. With the eGo and DS, the TH seemed to just be there. But I was with the Magma having that problem, and I saw a video where a guy pointed something out that I hadn't thought ot and decided to try.
I smoked 3 packs a day, Marlb Reds, for the past 25 years. I always smoked using "indirect inhale" - take a drag into the mouth and THEN inhale. I saw that video and tried the "direct inhale" - inhale as you take the drag, and that solved the situation all by itself on the Magma. Give that a shot and see if it helps at all. Did the trick for me.
