I don't get how it'd leak? Mine did first time, but I figured out it was because coming from the Doggy, I just didn't tighten the tank down enough. Since then, not a single drop.
A couple of weeks ago, I rebuilt, and wasn't really getting that great vape. Took a look at it before removing the coil, and noticed it was just too far above the air intake. Again, coming from doggy, it's deceiving, because the intake is so much lower than the screws, which I'd used to visually guage the height of the coil. Anyway, after rebuilding, and putting the bottom of the coil only about 1mm above the intake, it is absolutely incredible again.
You say you're using 1.96 ohm? Give it a try with (if you have it) 28ga SS, 2mm ID, 7 wraps, approx 0.58 ohm, and set it to a hair more than 1mm above the intake. This will make the top of coil slightly above top of screw heads. I vape it at 8.5W. I think you'll like it.
