how is HHV NETs on coils any better or worse than other NETs
As I remember
(2014) they were cleaner than most, easier on wicks/coils but there's a trade off. HHV's NETs didn't taste like a traditional NET, they're "different".
To me the tobacco nuance in HHV's NETs tastes somewhat generic, a flavor I've come to associate when TA
(Tobacco Absolute) is used. But the tobacco element in HHVs NETs is
unusually robust in flavor intensity, the tobacco nuance is strong. Most of their NETs are hybrids with secondary flavorings mixed in. NETs from vendors like NET.com, RTE, Black Note etc.. are made from TE
(Tobacco Extract) and yield a more refined flavor, you can taste all the delicate nuances of the tobaccos used. Note that my observations are dated, I haven't bought any retail NET in years. I use to broadly sample retail NETs as a comparison to those I was making back when I was honing my skills.
