I've got these E2 R4 cartos, and I have been vaping VG juice. Still trying to be careful not to overdrive the atty, but I keep burning the e-liquid when I take a big puff. Is that because it is VG? Would I be better off with a vg pg mix or just straight pg, or a higher ohm carto? I'm using a standard 510 batt with a 2.8 ohm R4, just tired of having to clean my cartos all the time. I also noticed when you take out the inner seal, it has a tendancy to leak, even when it lined back up properly. Thinking of a way to jet off the wick using a syringe and vodka without removing the inner seal.
