ditched the .75 R41 coil, wapped some tiger wire at .7, checked it top on, top off, fire button and spark, instantly broke the wire at the post....built a kanthal 1.3 coil checked, great...vaping fine at the moment, needs to break in, it really does get easier to build, but initially it is frustrating. I'll twist some more tiger wire up and try again later. Tiger flavor is almost up there with MM but will fit much easier on the chalice posts. good times, good times.
