i just twisted my first wire, if you're curious as to how it affects the build (per steam-engine), i managed to twist my wire 1.2mm in between each ridge (pitch), and 9 wraps with 26g kanthal A-1 gets me .35 ohm, and heat flux at 158W @ 7.4V, if i switch to non twisted 9 wraps, its .45 ohm and a LOT less W (like 55) and not even using anywhere near battery max juice to heat to "too hot" (again, according to steam engine), and if you wanted the same ohm with that wire not twisted, its 7 wraps, AND since its not twisted you get a lot less surface area, and therefore less clouds and what have you... but you do save battery life haha
