i really, really love the stainless steel cartomater tanks from vaperfexion. solid, beautiful, reliable.
then there's the big daddy and little mamma from big daddy vapor. those are super solid, and won't leak.
thing is...a tank is a tank is a tank. it's a matter of style and reliability. i still use my plain ol' dct smok tanks every now and then, too. obviously, i'm talking exclusively about carto tanks here. i used to swear by the vivi nova and vivi nova minis, but i moved up from an ego twist to a bigger, more powerful pv, and i've had no luck with wick based tanks since making the switch. so, i'm sticking with carto tanks, personally. however, if you like the wick style tanks, vivi novas are great, even if they do suck up juice really fast.
