can we talk plug gaps?

Crane claims there 8.5mm fire wire has 25 ohms of resistance per foot, but i have heard people say they have more like 300 to 400 ohms of resistance per foot. So i dont know for sure, they sure do look like good qaulity wires and they would match my coil and ignition box. But if i can get a little better spark by going with the taylor thundervolt 8.2mm wires that have 40 ohms of resistance per foot then i'll get em, or the msd's but the msd's are more money then the thundervolts, about 25 bucks more for the same wire basically, same resistance anyway.
