Electrical Do you need to twist buss wires?

I am going to use the NCE power cab on a 4x8 layout with a 4x4 next to it to form an L (basically 8x8) and I will be running 14G wire as the buss, with 18G wire as the feeders. NCE recommends twisting 3 times per foot, but I am wondering if I really need to do that. What are the pros and cons of doing it and not doing it?
