I've played with various "fancy" coils as well, (twisted, claptons, fused claptons, helix, etc.), and have had hit and miss results. For instance I have used a dual twisted 26g helixed with 30g that got gunked up fairly quickly one day, but the exact same set-up, including the same mod, atty, battery and coils built the exact same way vaped like a champ with the exact same juice a different time. Theoretically the non-traditional coils are supposed to vape better no matter what type of juice you're using because with those coils you are increasing the surface area of the wire as well as creating additional "channels" for the juice to seep down into, thus permitting a more efficient vaporizing of the liquid. Like I said, though, it always seems to be hit and miss.
