So currently I am using a protank mini on a ego twist. 1000mah ego dies too quickly but thats anoth3r problem. I was just wondering if there is a majority concensus on the best type of delivery system. My protank mini doesn't hold enough juice, it is constantly getting juice in the top part of the coil making it gurgle and spit, and for reasons I cant figure out the draw gets super tight for no reason (can literally be from one vape to the next and a world of difference. ) I am open to anything (married poor college student so no 150$ rba for me =/) thanks in advance to any input received. Best wishes, and happy vaping.
