Make sure you have some good batteries to go along with your cloud chasing. Im hoping you have already read about the Safety aspect of sub ohming, If you haven't then you really should check it out. When I say really should I mean you need to, It's always nice having two hands and a face.
Get yourself a pair of Sony VTC4 18650's and an ohm reader as well, most VV/VW devices won't read low subohm. I don't really want to suggest any builds unless you know what your doing..
