I have absolutely zero experience with dripping but some of the sub ohm tanks are juice guzzlers. My arctic drinks the juice even on lower watts (40w). When I run it at 60-65w like I prefer with that tank it's gone in no time. My delta 2 and atlantis do ok since I only run those around 35w. I will say my atlantis 2, at 40w, does pretty well. My subtank mini will be in tomorrow so will see how that does. My point is even with the tanks you can still go through some juice depending on your vaping preferences.
