By the way, I received a Cisco spec 501 @ 2.0 ohms, which I popped on my XL about three days ago. At first, I couldn't really see any difference when compared to the Vapage Hybrid atty. Until today...
I just went for a walk to get away from the markets for a few minutes, and my XL has started putting out quite a bit more vapor, and the flavor coming out of it has increased, dare I say, exponentially. I filled the bottle on the XL with VCV Nightshift 6mg over a week ago, and it is down to about 25% full, so I've had a LOT of vapes of this stuff from the XL using the Vapage Hybrid atty, both indoors and outdoors.
Let's see if this holds up in the coming days, or if it is a fluke based on atmospheric conditions.
