That one is 1.4ohm 28g Kanthal - 8 wraps
I also wet the cotton with juice and glue it in place.
The only time I had a leak was when I was messing around with it changing ejuice flavors and it wasn't tightened down enough. I tried blowing through the air hole, etc. but ended up breaking it down and making sure everything was lined up and screwed down tight.
Overfill - that can cause leaking and gurgling... If I turn the tank on it's side I should see a bubble. In an all stainless tank though, that wouldn't work...
Hope you sort it out soon!!!
I haven't had leaking or gurgling.... yet.... *yet* being the operative
