I have been using rebuildable drippers for about a year now. I purchased a duel coil recently and find the flavor is more intense verses a single coil. Why? My builds are 1.5 Ohms. When I use a single coil my volt setting is 3.5v. On a duel coil my volts are 4.5v cause 3.5v takes to long to warm up. I suspect the flavor is better because the coils are vaporizing my juice at a lower temperature as well as a larger surface area. But, am I correct? Or is there more going on?
