Right.

WRONG! Lightning is NOT a DC event. It is a TRANSIENT, with its energy 
centered around the AM broadcast band and extending for several octaves 
either side (that is, from about 200 kHz to about 5 MHz). INDUCTANCE is 
what matters, and that is proportional to length. The only benefit of a 
bigger conductor is that the conductor can discharge more of the event 
before it vaporizes. :)
