I'd love to have a sub ohm tank I could do mouth to lung hits on,like the kanger mini,I now use aspire mini's and isticks..I can do,I think it called slipping,hits..My old abused lungs just don't like serious lung hits..Also I seem to get more flavor doing mouth to lung but from what I read the new kanger subs are super for flavor and vapor..Can you set the smaller hole about half way down and use a narrower drip tip?? or does that defeat the purpose of a sub tank? I'm down to nic lever 5 as it is now...Any advice from sub tank users,especially like the new kangers,mini or nano,thanks Bob
