Hey everyone, Ok here is the deal. I bought a kayfun and I built a chimney coil build.. The flavor is outstanding.. Flavor is definitely a little better then my Nautilus Mini. Problem is the vapor production is weak. My Nautilus mini produces much thicker and dense vapor. I really want to love the kayfun but find myself always going back to the Nautilus Mini for vapor production.. So my last two builds were of chimney coil builds. First one was 1.7 with 28g 14 wraps.. Flavor was great but vapor was kinda weak.. So i thought I should lower the ohms.. So I built a 1.3ohm build 28g 12 wraps.. Flavor is still outstanding but vapor is just not there.. I have tired too much cotton and very little cotton.. Both wick fine but just don't produce that satisfying vapor I get from my nautilus mini.. I bought the kayfun so I can product more vapor then my Nautilus Mini and it seems it just can't do it.. I have done countless builds on the kayfun and finally found chimney is the best on flavor so I want to stay with it but I need more vapor.. So my question is am I doing something wrong or does the kayfun just not produce that much vapor. Oh and I have the air hole screw completely out..
