What the others have already said..... Single coil, build at higher ohms, or decrease your vape wattage.
I use a .2 ohm single coil stapled clapton on my Avocado 24 and it still drinks a lot of juice. I vape between 60 - 80 watts.
I do not wick my cotton into the tank. I cut the cotton tails just above the juice holes. You do have to tip the tank to feed the juice into the wick. For me, this is no biggie because I tilt my tank to vape anyways. (Picture drinking out of a bottle)
I find this wicking method does consume less juice because there is no cotton in the tank to take up space or soak up all of the juice in the tank.
