Not enough vapor less effect

[Thrasher]

When I used vv ego's I usually stayed around 1.8 ohms.
Might just have a bad tank, dunno.

What was your setup back then?

I'm using single coi.

But my question is, I've seen tons of people using the spinner 2 with dual coil evods without problem, and with a lot of flavor and vapor production. And the evod BDC is included in evod 2 starter kit which got batteries at 650 mAh 3,7 volt, and that works just fine. So why won't it work for me?
