As being an experienced high wattage vape user, even I can forget the properties of liquids. In the Cleito 120, you may want to use a 80VG/20PG juice instead of max VG if you want better flavor. The PG will help to carry the flavor. Some flavors will burn off at the wattages used by this tank and they will not be as good. The thinner liquid will also wick better than the thicker max VG if you feel the need to push the coils to the 160 that Aspire states the tank will go. Also, avoid juice with a strong sugary profile. At the higher wattages, you will gunk up and ruin your coils faster and you have no way to rewick or burn off the build up.
