That's the gist of sub-ohming. More coil surface, more power, more heat, more vaporized juice, more flavor.
Cloud chasing is just an affectation.
And I'm not convinced the pinnacle of flavor lives only at the bleeding edge of low ohms.
sub-ohming is largely a relic of using mech mods where the only way the user has any way of increasing power is to lower the res of the coil. With regulated mods, it doesnt really mean anything...at least in my opinion. Not saying mech mods are obsolete, its just a different way of doing things.
Large clouds generally require large airflow which, in general, is the enemy of flavour! Thats why RDAs (and RTAs for that matter) that generate insane clouds tend to lack a bit (or a lot) of flavour.
