Pretty much any tank available today could be either a sub ohm or a "non sub-ohm" tank. The difference is in the coil used. FirSt off, decide if you prefer MTL or DL vaping, do you prefer rta (make your own coils) or premade coils. The rta will give you more flexibility and choices, the premade coil tanks are a bit easier to use but you may be limited in the coil options. These days most coils are in the "clouds,bro" category which is exactly the opposite of what you want. One easy tank is the Tobeco super (mini) tank family, they use the aspire coils so you can use the 1.8 ohm triton coil or the 1.0 ohm Atlantis coil in it. There is a rta version of this tank as well. I have both versions and like them both, they can handle any % ratio juice you throw at them. The rta tank could be a very loose draw MTL or more of a decent DL tank. The pre-made coil tank could be used either way, depending one the coil you install. If you look at the bottom of the coils, you'll see either a smallish air intake (triton 1.8 ohm coil) or a fairly large air intake like most of the coils available today. Another tank to consider is the Melo 3/mini tanks. I like them both. I read good things about the iJoy Reaper as well but I haven't bought one yet.
