I've been running a carto tank setup for about a year now. My local B&M stores carry the Smok brand cartos. I've noticed that when I try a new juice at the store it will taste one way, and when I load it up in my carto tank it will taste different. Like some of the flavors are being muted. I recently purchased a Nautilus tank setup and the flavors have returned to what I remembered in the store. However, I seem to eat through the 1.8 ohm atomizers like crazy to get the vape I like. Aside from going with a rebuildable, is there any tank setup that would allow me to run the voltage at 4.0 to 4.5- which is where I usually run my carto tanks to get the warm thick vapor I like?
