Im asking for direction from my fellow vets with finding a great MTL tank for my Kanger Top Box TC 120. Without understanding that sub ohm is for big clouds puffed straight in the lungs I picked up a couple of Smok TVF4s. I'm trying to stay away from chain smoking and am lost trying to find a 1 to 2.5 ohm big tank with an optional rebuildable coil deck. I used to use the Kanger dual Aerotank that aren't on the market anymore. Please help an old Swabby out! Thanks!
