Your opinion on equal length spark plug wires?

My dad raced for Grand Spaualding Dodge outa Detroit back in the 60's n 70's and the old school race days they even tried to keep the plug wires same length for that reason but my dad always thought it was a waste of time so he tune and tested his drag car with 3 different length wires and the car didn't miss a beat or more importantly it didn't suffer with his ET's, now I am not a scientist of any sort but like I read earlier electricity moves so fast in that short of a distance I couldn't imagine it would be beneficial to have same length wires. I have learned that keeping your wires separated and not tangled together can help prevent spark traveling to other wires which can cause weird stuff to happen, but with hi-tech wires they make today I have never had troubles with that. I use Taylor wires because they seem to never get hard after being exposed to heat/headers and never spark travel.
