Just put a 2.0 mm ID coil in the Xeta....(6/7 wraps, 1.09 ohms, 28/38 nichrome 80). Vaping at 15. 5 watts, good flavor, strong throat hit but still not quite there for me. One problem is the little black plastic air flow control/restrictor......when position for an acceptable draw (for me), the little turd blocks the glass on the boro from sliding down for a refill.
There, slid it all the way open, doesn't block the glass anymore, draw is acceptable.....sort of.
Next up, 28g plain nichrome followed by plain 30 g nichrome.....we shall see.
All in all, it is a good bridge with good flavor and TH, easy to build and wick, much better rba bridge than all the others I've tried (and I've tried several).
