There needs to be a "sticky" on throat hit.
There are only TWO things that provides 90-95% of throat hit: warmer vapor and nicotine strength. More PG vs VG, additives such as PGA, only change the throat hit by a small percentage. And that may be all a person needs, which makes it a little easier.
Warmer vapor comes with more power, which is provided by more powerful batteries: 5 volt and variable volt batteries provide the warmest vapor and thus much better and consistent throat hit over a much longer time frame. If a person has not vaped on a 5 volt or variable volt PV in comparison to 3.2v - 3.7v, there is no way they would realize the significant difference. The other part of the equation is obviously a higher level of nicotine, generally in the 18-36mg range.
LR attys can also help with smaller battery PV's (3.2-3.7 volt). But they have a shorter life span and are more inconsistent.
