cpat if it was flooding and leaking the replacement coil may have been loose. Always before you fill a tank be sure the coil (on the center post in the tank) is screwed on good and that the condom is all the way down. If it is loose it will cause leaking. My 100% VG hasn't leaked any.
Hi cpat! I have had the same experience with 100% VG juice as Evie above stated. So far no leaks, so I would suspect that something was probably loose. Sometimes when you unscrew the mouthpiece to rinse or wipe it, you actually unscrew the center post a bit, too, without knowing it.
You do have to also be careful not to overfill. I have accidentally done that a time or two by not having the tank level when filling in a hurry.
As Evie said, I am on 100%VG and as long as I remember to slow down and keep my wicks wet, everything is good. Even easier with the thinner PG added juices.
It's great that you can vape the Halo juices, I wish they had some with more VG so I could join the party. Maybe soon they will, lots of companies are adding a VG line. But don't be afraid of non-Halo juice. I've tried just about everything and the Triton handled it just fine!
