The post above contradicts Ohm's Law.
Since he's got 0.7 ohms with his SS coil it's obviously a resistive wire. If it were 100% conductive he would have gotten a short circuit and thus be unable to do anything with it.
How fast the wire heats up depends on its thickness and how much power is applied. How good the heat of the wire transfers to the wick and the juice, depends on the surface area that is touching the wick.
Clapton wire and any kind of twisted wire will always be slower to heat up than using parallel strands or ribbon to achieve the same surface. My SS coils using parallel strands of 0.35mm (~27AWG) wire heat up faster, and also cool back down faster than the stock Clapton coils, or the coils that i made using Clapton style wire.
