They have a new design coming out with a bigger RBA. I think it's called the TF-RTA. A dual velocity style deck or some ridiculous looking quad coil deck.one of the few drawbacks of the tfv4....the tiny ... build deck. lately i've been ....ing around with the triple coil rta deck, and while the juice channels are bigger, it's still a very tight build. if smok would just make the deck wider (i'd gladly give up a ml or two of juice) i'd be totally happy.
