I'm running mine with 24g flat sixty, 2.5id and 7 wraps, coming out about 0.42... I'm using the smaller of the 2 air reducers (the one with the 2 holes in) airflow open just over half way, I'm finding the airflow nice and smooth and the flavour is badass, it's a warm Vape but not at all hot... As for flooding out it can be easily done, just try not squeezing the bottle so hard, if the juice comes up over the reducers is could flood that way, the juice well is pretty deep so get a fair bit of cotton in there, don't pack it to tight, make the cotton nice and fluffy and the cotton should absorb the juice fairly quickly and get upto the coil... Not saying this will 100% work for you but it's working for me... Be good to hear how others are running it...
