SInce you're making your own juice I'll assume vaping is your hobby more or less.
If that's the case - definitely get into rebuildables, RTA/RDA. A lot cheaper after initial investment, better flavor, a lot more options for coils/wires too.
If you're sticking to prebuilt coil tanks - Freemax Mesh Pro & Horizon Falcon are the two constantly mentioned as the best ones for flavor. Throw it on any decent 2 battery mod and you're good.
