Idk if you can really tell from the picture, but instead of just using 1 strand of resistance wire, here I'm using 2 intertwined strands. In this case, I twisted together a strand of 34g Kanthal-A1 and a stand of 36g Kanthal D.
Though vapor production was already excellent due to my "mac-attack" tweak, the dual coil vastly improved it! The most notable change in performance is how I no longer need to take 10 second drags to get plumes of vapor

. Only thing not perfect with my current setup is that I'm using a fairly thick VG juice (Butterscotch from COV) with 400 mesh. Regardless, it's wicking just fine if I tilt it on its side. Getting some 325 mesh in the mail from Urq later this week, as well as some from Armen at a vape-meet here in LA on Saturday.
Here are a few more pics...
