Do you have over wicking with the updated topper or with the first one? The new topper is very efficient in handling this issue.
Perseas, I've been using my new Heron v2/Ultem with the older double hole topper on my Paps 4 for much of this past week. It was so solid, reliable and
absolutely leak free, that I was about to order a Piccoloid to carry around as my portable in-the-pocket vape, something I would never do unless I used a readymade coil. And then the problems started. Out of the blue I started to get heavy leaking during a bout of heavy vaping (usually the result of watching a gripping TV episode!). So the next day, I cleaned up, re-filled and started again. Now I was getting dry hits. Everything seemed fine with the wick. I had originally wicked using Qorax's video as a reference. So I replaced the topper with the newer single hole version, re-wicked using Qorax's new topper video as a guide again, and.......still dry hits. I checked and juiced up the wick again. This time it was fine, but I guess only until I dried/vaped out the wick and then dry hits again.
What's going wrong? Is my wick too long? Too dense? FYI I'm using 70 VG juice and cotton. Seek your comments and advice.
