Good point. I guess it is to recreate the analog feel more. Several things contribute besides optimally primed hardware. PG itself, no nic, will give me a TH because PG irritates my throat, and the more I vape it the bigger the TH...because of the "damage". I don't need that. Since I use only VG juices now, TH is a way for me to tell if I'm getting significant nic right away. Sort of a gauge. But then there is something nice about that burn, like oh yeah I got some that time. Since analogs, unlike the NRTs, work perfectly every time for getting nic, its the internal meter than says how close to that efficiency I am with the vape. Of course, we also know that absorption and and general delivery are not like an analog, so this pursuit of the best TH is likely just holding on to the illusion of analog delivery. In general, if there is no TH I will probably just keep vaping. If I do that with every hit being a strong TH, then I know I will be truly buzzed in a few minutes, and not always pleasantly so.
