I bought a smoktech ego kit and a dual coil tank a week ago. My first PV. I could use some advice on the tank. I used the carto that came with it and it was decent for about a tank full and then it started to taste kind of burnt and not much flavor. The one it came with was the single hole ones. Ive read that those have a tenancy to do that. Would i have better luck with the triple holed ones? Also, any other advice on how i could make my vaping experience better (not that it has been bad so far).
