For my
kayfun I get great flavor and nice dense vapor using a micro coil. I use 28 gauge kanthal wire, (28 gauge is what I use for most builds) I do a 5/6 tight wrap on a 3/4 inch screw driver then I compress the coil with tweezers and torch it while compressed. Let cool then connect it. This consistently gives me about a 1.0 ohm build. When building kayfun, allow 2-3 mm for the coil to sit above the air flow valve or you will get flooding. I wick with a sterile cotton. I must say my kayfun and taifun give me some of the best flavor and vapor I've had. The kayfun is very much worth getting as it won't disapoint! However build and wicking is Important if not done correctly it can be temperamental. If you are getting a gurgle it's due to the wicking. I highly recommend watching some you tube videos on how to build and wick the kayfun. Once you get the build down, nothing compares to it! In fact, I like mine so much I just ordered another one! Kayfun and taifun are both a great choice in RBAS. I think if you choose the kayfun you will be very happy with it. As for wire, like I mentioned, you can't go wrong with 28 gauge wire. Hope this helps. Best wishes
