" Here is some simple science that some already touched upon but didn't address directly. Popping and spitting is caused by your coil(s) being drowned. The vapor pressure is pushing out of the liquid and taking some of the hot liquid with it. Ever fry bacon? The steam quickly pops from under the grease taking some of it with it. Same thing is happening in your build. To simply help prevent this, don't drown your coil(s) by making your wick more efficient.
I'll assume you are going to use cotton for wicking. With cotton, less is more. The biggest mistake people make is cramming a big ass wad of cotton in their builds. Cotton is good at holding liquid, wicking it, not so much. To find the saturation point of your cotton is easy. Don't put the tails of your wick under your coils. Vape as normal. When you get a dry hit, take a look at your wick. Do you see the whitish part near your coil and the rest is soaking wet? That is the excess cotton, the place where your liquid goes to die, never to be vaped. Snip that excess cotton just past the dry area. Now your wick is efficient. just make sure there is enough wick to touch your deck so it acts like a mop.
The other cause of liquid in your draw is called "juice creep". As many have mentioned, using a big bore drip tip helps considerably. The reason why is that as your vapor condenses in the drip tip air channel, it condenses on the sides. Surface tension will keep a drop in the channel and your draw it up when applying negative pressure (inhale). A wide drip tip doesn't allow the drop to touch all the sides, which allows it to remain in the air channel. With a larger diameter air channel, the condensation just drips back down. Drip tips air channel is restricted by the drip tip connector. The drip tips that are larger after the connector allow that condensation to flow back down like a funnel instead of up like a straw.
Hope that helps. Cheers mate."

Thanks man!!
Spitback is such a weird thing. You'd think you need to drop wattage, but it's often corrected by raising it.
Generally it can be dealt with by playing with wicking / wattage. Use less wick and use more wattage. That has been my experience at least!
