I'm still a newbie, been vaping for just shy of 2 months. I have zero complaints for the results I've gotten w/ the investment I've made so far. I have a few ego clones I roate w/ about 10 CE4/CE5's. I've learned the ropes to not have them ever leak, and I only vape lightly so none of them are clogged or icky. Now I've been thru quite a few flavors, and I finally found something I consider to literally be delicious - a vanilla ice-cream / extra blueberry mix. I do long mouth holds, followed by a slow french-inhale (mouth into nostrils), and this is how to really taste a flavor IMO, when you're literally smelling it as you inhale. It reminds me of the aroma of a fresh blueberry muffin. Now something I've noticed, is if I take more than a few hits in quick succession, the coil obviously gets hotter and the taste changes. I can't say it's a burnt taste, cuz it's not getting to that point, but the deliciousness diminishes until the wick resaturates. It's not really a problem because I'm constantly rotating between at least 2 flavors, but this is the 1st flavor I've been able to really notice a difference like this. So is this a case where having variable voltage would allow me to pinpoint the sweet-spot I'm looking for here?
