The other part of the equation is the juice. Nhaler's High Voltage juice
has gotten a lot of very positive feedback on the forum for flavor. It's only offered in what I consider to be VERY low nic content (12mg). But when they come out with 24+, I'll be all over that. Since high voltage is a "flavor killer" (Whoa, how can you kill something that's already dead?) it only makes sense that the high voltage juices would need to be more flavorfull.
Truthfully, many (if not most) folks seem to do just fine with a lower nicotine concentration when vaping at high voltages. I'm not sure why, but I'm perfectly happy at 12 mg when vaping at 5 and 6 volts. If I vape at 3.7 volts, though, 12 mg just doesn't seem very satisfying at all.
In any event, it may be worthwhile to pick up a few sample bottles of the high voltage liquids and see if that makes a difference.
You may also be a good candidate for DIY exploration. I have been known to add some LorAnns or Capella to an eliquid that didn't have quite enough taste to suit me.
