I am pretty new to vaping also.  I have found the Evod's the most reliable.  Only time I had gurgle/flood issue is when I needed to change the coil head.  Used thicker VG juice and it was just caked up on the wicks.  Nowhere else for the juice to flow but out.  I also love my I clear 30, however, it is so touchy.  Some tanks you want to screw the coil head tight, other's just "finger tight".  Just practice I suppose.  I also enjoy the MT3S.  It is a bigger Evod, great venting.  Sometimes so good I stick a small piece of electrical tape to cover a hole up.
