I'm not sure if anyone has mentioned this yet as I was too lazy to read the entire thread (Sorry). I began vaping about a month or two ago and am still on eGo batteries and a mix of kanger pro tank minis and kanger evod glass tanks. I noticed something over the course of the last week that might pertain to your problem. When I'm out drinking or in social situations people often see me vaping and are curious. This sometimes results in them asking to try it, which I oblige.
However, I noticed when i let other people try it my tank either starts leaking, or it makes a horrible gurgling. I've come to the conclusion that it's because they're sucking way to hard on the tank which results in the juice completely flooding the little chamber where the coil is. Your problem may just be that your vaping technique is wrong. These are not "analog" cigarettes and do not require a hard pull, instead light puffs for a mouth inhale or a very light inhale for a lung inhale will suffice. I can't imagine upgrading to a RBA or a more expensive vv/vw mod will solve your problem if this is the cause. Then again I don't know because I have not upgraded myself..... yet...
