Oh ok for some reason I thought the thicker the better taste when vaping at high wattage thanks for clearing it up.
The thicker (VG) ... the more vapor in general. Actually ... PG tends to be a better flavor carrier in many juices. The sweetness of VG can "mute" some flavors. Some studies however have pointed towards VG being an overall healthier vaping liquid. But the studies of e-liquids is still in its' infancy so I'm not making any medical claims by any means.
Bottom line ... you can vape higher VG juices in the latest generations of tanks (subtank included).
