You're doing better than I managed, it took me four builds before it stopped pissing e-liquid out of the airholes. And it holds a lot of juice - especially when it doesn't.
Eventually I followed the build of Bloody Good Vaping on the Big Fogger (the v4 on steroids, I think - deck certainly looks the same). As earlier poster noted, wicks rising straight out of the channels, arcing to coil and over to opposite channel.
It is tricky to judge the right amount of cotton, between avoiding a flood and choking the wick. Not so forgiving as a Kayfun. When it does work though, it's a hoot!
