MTL or mouth-to-lung kits are ideally suited to closely match the smoking experience with a tighter draw.  MTL vape kits tend to use the small 10ml bottles of 50/50 liquid; thinner with higher mg of nicotine.

Dependent upon the coil choice, some kits like the Aspire Nautilus GT have coils suitable for a higher power vaping and a direct-to-lung DTL style.

MTL kits make a good starter choice for those looking to stop smoking or were heavier smokers.
