I use a 2mm drill bit to make my coils on my Igo-L. I use 26 gauge A-1. A 3 wrap coil ends up at about 0.7ohms and a 4 wrap ends up around 0.8-0.9 ohms. Then I take about a 1/2" wad of cotton and roll it tightly, much like I do with stainless wick, I spend a bit of time on it. Compress it pretty tight, then slide the narrower end of the cotton in from right to left so I can pull the thicker end out from left to right when the wick is dirty or burnt, or when I want to change flavors. I probably re-wick daily on average. The coil is a couple of weeks old. If I start to taste metallic hints, I re-coil.
