Anytime there are any electronics involved, then I recommend a RACING suppression core plug wire. 40 to 50 ohms a foot is for racing. 150 ohms per foot is street car stuff and can hurt your cap and rotor. In the case of a Vertex it can hurt the internal coil too.
The only real reason to run solid core wire is longevity. Unless you slice it or melt it, solid core lasts forever. The suppression core stuff WEARS OUT electrically. If you have electronics, it's worth replacing your plugs wires every other season and your coil wire a couple of times a season.
