I would have to be sure I got one with the extra tall glass as the RBA won't fit a BB without it (the BBB it will fit). I'm just not an RBA fan. I like my bigger RTA decks to work on, and I'm not sure the RBA would be worth the effort, especially with the smaller volume (I would have to check if the volume held goes up with the taller glass). It's a well performing tank with the great clouds Smok is going for, and the flavor is pretty good too. I certainly won't dump it, you never know when you need a different tank for something.
