I am new to this forum, I have a Z-atty pro, read and tried almost every thread out there,but nothing worked for me maybe because I vape Alcazar cigar, this seems to work for me,I twist 32 gauge wire for coil,I make the coil on a drill bit the size of the wick hole four to five wraps,then I attach it to the atty then fie the coil for even burn,(pro vari mod) then I use all cotton pipe cleaner about 13/4 inches long ( I boil them before using ),then I tread pipe cleaner though coil and cut it to the proper size,prime the wick and fill the tank and you are good to go,I get good flavor and good cloud,to change the wick cut it right below the coil and pull that part out and thread the piece out of the coil,dry fire the coil to clean and thread another wick in (pipe cleaner) . the coil size depends on the size of the pipe cleaner,the pipe cleaner will expand sum when full of juice. Hope this helps you for good flavor and and clouds
