Ooooo... Nic in the eye! Never did that one but I suspect you'll survive.
Theoretically, given the same nic, you should be getting more TH with the higher PG, but there are other ingredients that affect it. That said, I haven't heard a whole lot of love being cast Halo's way for their
juice. Maybe that's got something to do with it. Try one of the higher resistance heads. They seem to produce a fuller vapor than the lower ones. Don't be afraid to turn that sucker upside down if you need to. Unlike, for example, the Vision Stone
tanks, they won't flood or gurgle on you. Lay them on their sides or anything and it only makes them vape better.
Look inside the head. There's a thin sleeve of woven silica around the coil. Make sure it's centered. It's pretty flimsy and could possibly be scorching or something. Just move it back in position if it's gotten knocked askew. Otherwise, you don't ever need to pull that rubber cap off unless you're dry burning it.
One thing I did find out though, the rubber cap has a top and bottom. Not so much the rubber cap, but the metal piece inside of it. It should be in the rubber tube with the flat side against the atomizer cup and the hollow side toward the drip tip. I'm not sure what the practical implications are, but it could conceivably make a difference in temperature or leak-resistance or something as arcane as all that.
Give it a shot. Lay it on it's side overnight and let it soak good. It'll surprise you. It does benefit from a little break in and the second tankfull tastes better than the first.
..regards mafig ps i rotate 4 PVs and the PV i use the steel carto after 6 weeks still going strong unlike boge or kanger carto(with filler) i need to change after 2-3 weeks of usage
