I just upgraded my equipment but everything I got is sub-ohm. Since these are my first sub-ohm and I have heard that they produce large clouds of vapor, I would like to know which reg battery and tank would not be so conspicuous in public. I know ProVari is considered high end. I like large tanks that I can travel in the car and not have to fill real often. I would prefer a glass tank so I don't have to worry about what juice I vape. Can you guys please give me recommendations on batteries and tanks that not high maintenanace, known not to have leaking problems, are reasonably priced, and have high reviews? I think I need to add this to my upgraded equipment. I am looking for GOOD equipment at a reasonable price. Thanks
