right now i have a 3/4 wrap of 28g at .08Ω on the 1/8 wick and vaping on my mechanical mod. this is really working excellent and has become my favorite set-up up to this point. before this i was loving the 30g, 4/5wrap ,1.1Ω on the 3/32 wick, although both are awesome i prefer the 28g. one thing i dont understand stringer 63 is why you are getting a hot vape, just today i was saying to myself just how cool this set-up is running. the top cap is completely cool, just a tiny fraction warm if anything. i kind of was thinking that compared to ss mesh, that maybe the ceramic absorbs so much heat that the device actually stays cooler. when i used ss wicks i made my wicks very solid, i mean i used to cram over 4 inches of mesh into my wicks and this also seemed to keep my device cool as well. some say that when they have done 28g and low resistances they liked it but it was to hot. so i am not sure why some found it to hot while some stayed cool. i thought maybe it was the way in which the wicks were configured, but with you saying that your device is hot with the ceramic and 28g, it maybe something else. i would tend to think now it is from loose coils, for if the wick isnt absorbing the heat, then the heat transferes somewhere else. anyways 0.8 is the lowest i have tried so far and might give a 2/3 a try but .06 has always been a little to potent for me, but 0.8 seemes to be working just fine, great flavor and big clouds. maybe the size of the atomizer chamber might vary in temp, the ac-9 is pretty large so maybe it has time to cool off. havent tried 28g and sub-1 coiles yet in the aga because of the 3/32 wick. i still am debating whether to drill out to 1/8 on the aga. also stringer we are comparing different ceramics here as well, fc 2000 compared to the fishs, i still dont know if they are the same.
