zen recommends 4 to start with, then try one less or one more from there...it all depends on what voltage you prefer to vape with.. I use 3.7 to 4.2v with most of my mods, and atm, the z-atty-g has 4 wraps 36ga nichrome in it, guessing its around 1.8 to 2 ohms........ two rebuildables I have...one has 3 wraps 36ga nichrome dual coils (reads 1.1 ohm on my provari), for 3.7v vaping, another one has 6 wraps of 32ga kanthal for 3.1 ohm vaping at 7.4v.. (those 2 arent z-atty's though too)
How did you do dual coils? Two separate strands of wire?
