The vcmt2 is very very decent, as was the original. I was sceptical with top airflow but as the year has worn on, so has the quality of top airflow tanks. The dead rabbit RTA in my opinion is just about the best out there, although Its not designed for single coil. That's not to say that you can't single coil it, it's just a little bit shit. The @WOTOFO serpent elevate is miles in front of any single coil top airflow available on the market at the moment, and is a proper little flavour machine, easy to wick, no leaks or gurgles and it looks pretty decent.
