I have been vaping for about 2 years now and within the last month or so I have got where I am building my own coils. I haven't got the big mod yet or upgraded like that which I will be soon so for right now I have been rebuilding my tanks that go on my EVOD and dream vapors. I am using the kanthal 32 ga and organic cotton for wick but I notice that the air flow is like restricted when iam pulling where as when I would get a new tank or coil from store it was a nice air flow when pulling I still produce vap but just real restricted feeling any suggestions on why and how I can open it up again. Thanks.
