i have a bunch of these and love them. They are one of my favorite RTA's. There are two ways to wick them (that I use) that keep them from being a faucet.
When using high VG I dress the wick down until it just touches the deck. Then saturate the cotton and fluff them out, screw on the chimney without the glass and use some tweezers to further fluff it out and seal the holes and dress it all in nice, then unscrew it and put the glass back on. With it being wet it generally maintains its shape.
Only let it touch the deck and not lay over. As the juice gets wet and cotton gets heavy the tanks vacuum will be broken by the weight of the cotton dangling and it will leak like a California dam.
If using lower VG juice I will wick it normally at the coil but tighter into the tank and only let it protrude about 1mm. In this instance saturate the cotton, screw it together without the glass and bow tie fluff it up and then assemble it with the glass.
I always fill mine with the airflow closed and then prime it a couple of puffs to get the suction in the tanks squared away. With the airflow holes being so large you really have to fill the 4 holes from the build deck into the tank full and makes sure there are no places for juice to leak up, because it will. It also works really well in this particular tank to position your coils very low on the deck as close to the air holes as possible.
When I get home tomorrow I can build them up in each instance and post pics if that helps. These really are great tanks. I use CB V2 and whatever pads i pick up when no CB V2 is available. I am surprised those coils don't short out being as large as they are.
