what resistance are you aiming for?
I wouldn't use ekowool to wick a genesis atty
with cotton you just have to put enough that it fill less than half the wick hole, you don't want to over do cotton as well as not put enough cotton
the roll of mesh you have to torch the mesh before your coil is on it, then when the coil is on it you have to pulse the mod till you have the coils running red from the inside out with mesh you also have to worry about shorting on the bottom of the tank
Me personally I have a RSST, genesis style atty, at first I used to use cotton, but now I use cable wire as my wick.
I am firing my rsst at 0.8ohms with NO dry burns
with genesis style tanks you also have to be aware where you wick is inside the tank so that your tilt your mod while you vape so that the wick is immersed in liquid
