Ok, so the 3 main true tests to any juice is VTF(vapor production, throat hit, flavor). I have been vaping for over a month now and still can't ever feel and throat hit...on any juice. I have about 30 different juices from 4 different suppliers, I have probably tried half of them so far and have yet to experience any throat hit. I have also used different ratios of VG/PG, and have even added PGA(as recommended by a supplier and seen on other reviews) on some and it doesn't add any TH, just the nasty taste of Everclear. Now here is the thing..I vape at 6v with a dual coil carto. Everyone who asks to try my roughstack will cough when they first try it because they see me taking a long draw, so they do the same. The first comment is how heavy it hits their throat. For me...nothing. Could it be that my throat is just used to smoking for so many years? Does anyone else experience this?
