What really sucks is I would love to go to an actual brick/mortar store where they could teach and show people, but almost all of the vape shops around here are just hole in the wall joints, where they sell everything from cigarettes to hookas, you know?
See if you can find a good vape shop near where you live.
If you smoked cigarettes in the mtl style, you will probably be best suited in the same style vape-wise.
Good atomizers there are the Aspire Nautilus 3 and the Innokin Zenith II.
They obviously use their own coil system, but they have been around for many years and will be here for many more years.
Typical MTL coils from these two brands are Nautilus 0.7 mesh, Nautilus 1.0 Mesh, Aspire Triton 2 1.8 clapton.
For Innokin, it is the Z coil that fits in the Zennith II tank, what we mostly use is 0.6 dual coil, 0.8, 1.2 and 1.6. 0.8 gives a slightly warmer vape compared to the other three.
PS, pre-wet the coil before you put it in the tank, and preferably leave it for 5-10 minutes before you use it so that the coil has absorbed juice. Set the mod to the recommended watt strength that is recommended on the coil package, preferably start in the lower range.
There may well be others here who have other good solutions for you.
