When I've tried salts, I found they were detrimental to coil life.
I was thinking they might be a good solution at double or triple my usual strength at trade shows, where I couldn't vape as much as I normally do, but since they consistently made my coils taste burnt within a a couple of days, I gave up on them. And no, it wasn't the flavors. I even tried some completely unflavored salts that I made myself later, in the gear I usually use and had the same issues, albeit not quite as fast.
