Ignition Wires And ohms/ft Question

[hooD]

When I was comparing different brands of ignition wires, I saw that the ratings of ohms/ft varied widely from 25 ohms/ft all the way to 1500 ohms/ft. 

What is the importance of this rating and can someone explain this.

I'm considering a set of Taylor Spiro-Pro 8mm wires which are rated at 350 ohms/ft.  Are these decent wires?

the more resistance / ft the weaker the spark when it gets to the plug so less is better , the old way was to use stranded copper core but it creates radio interference so now they use the sprial core to minimize resistance while keeping interference low
 Taylor are bottom of the line , Accel & stock 7 mm are worse but MSD or Moroso are worth the extra $$
