When I first used mine, the hits were drying out faster than I would expect and the vape was suffering. This was with 100vg. When I changed it to line up by screwing the coil on the base instead of the chimney it helped. Maybe it was a coincidence though.
These coils have a lot of wicking material I've noticed and can take a bit to get fully saturated. Some folks say to start vaping a new coil at a lower wattage to break it in, which is a very good idea but the reason is not to break the coil in. In my experience they don't need any break in period, but wicking will happen very quickly if you heat up the coil since it thins the juice and makes it saturate quickly. So by starting at around 11watts until you get good vapor coming out it will fully saturate the wick without burning any of the wicking material. And don't take really long puffs even at 11 watts until the coil is saturated. Of course at 11watts it won't be blowing clouds, but this is just to get the coil full of juice. After the head is fully saturated it will keep up with juice flow great (and the heat of the coil is a big reason this happens). This happens quickly, so you shouldn't have to take more than 5 to 10 puffs at low wattage to get the coil working well, and these puffs should be done fairly quickly with a short rest between puffs so some heat remains in the coil (but not hot). I'm making this sound difficult, but it really isn't and only takes a minute or two.
I have found that just letting cool juice sit in the tank can really take a long time to saturate the coil, and this is especially true with high VG juices. And if you don't fully saturate the wick before putting 30watts or above to it, there is a very good chance of burning the wicking material. And burned wicks never unburn, so that will be a nasty coil the rest of it's life.
Anyway, this has been my experience... YMMV, but it has worked for me to quickly get a new coil vaping great with the atlantis.
