You can do both with the IPV4 too, at half the cost and twice the battery life..I thought that too until I borrowed a buddies SXMini 350J mod. Used it for a couple days and bought one (ouch, expensive), but now, well I love the damn thing for both temp control and regular kanthal builds.
Sort of the best of both worlds
