Guys and Gals,
This is a tip in order to reduce dry hits if you are experiencing any. Just to be clear, Ithaka under normal circumstances and setup right and you paying attention to your suction habits can be vaped without having any dry hits. But since I use 100%VG and chain vape at high voltages with dual coils and don't like to open my mouthpiece a lot, this can help

.
As you know the basic feeding ring can be brought up or down around the rebuildable part without causing leaking because there is a seal at the base (the positive lead o-ring). Therefore as Imeo has shown us in his videos if you bring it up it will make a cooler vape and makes the basic feeding higher. Forget the cooler vape for now. The act of screwing the basic feeding higher and closer to the top of the ceramic housing has 2 effects:
1- Basic feeding notches are closer to the coil
2- mouthpiece base is closer to the coil
Which means you will have a better feeding either by using the basic feeding or by opening the mouthpiece. Then you will not have the problem of opening the mouthpiece too much to feed since the liquid has to travel a smaller distance. Plus, suction works faster when you are inhaling and liquid reaches the coil with a shorter distance
Now for the cooler vape. A very easy solution is to make you coils higher. This will not interfere with the liquid reaching faster since what you care for is for liquid to reach the cup, and from there the suction from the center pin will shoot the liquid through the coil, no matter how high it is. So when you are building your coils, either X or parallel, make sure you keep it loose and make it high enough to the closest point of the mouthpiece hole, when mouthpiece is fully closed. A very easy way to do this as well is to stick a wick between the 2 coils of an X, and this will make your upper coil automatically higher.
Now for the Disclaimer. It needs practice because this is not problem free solution. IT CAN FLOOD. I was using 1.5ml wicks in the channels but when I used this method ithaka started flooding like crazy and liquid going into the center pin. So what you have to try is different wick sizes and different positions of the basic feeding ring to get it right.
Enjoy!
