Hmmmmmmmm, considering 3 years ago the technology and equipment available to us at the time???? A Kayfun V4 at 1.5ohms at 12watts gives 3x the amount vapor and 4x the amount of flavor a cig-a-like from the first versions of Blu could deliver. It is all in your perspective, the coil, coil chamber, and airflow are all still the deciding factors, not the watts, not the clouds, not the VG. Knowing how to build a coil on the strengths of the device you will use needs to be looked at first to get the best flavor and such from any device. 3years ago, I remember the best vapor and flavor came from a LR 306 dripping atomizer on a bottom fed Reo Mod with a 10amp AW IMR, the 306 low resistance at the time, was a wow 1.5ohms.
