At the risk of igniting debate I wanted to offer an observation. I act as the "wrench" for an annual WI bike trip and see broken spokes every year (22 yrs and counting). 80% are drive side spokes broken as a result of chain damage between cassette cluster and spokes. Almost always they are on wheels laced with the pattern shown in the second photo (black freehub) --presumably because the chain wedges in very tightly. I rarely see the same thing on spokes laced as shown in the first photo (silver freewheel hub) --where the outside spokes don't tend to wedge the chain deeper into greater damage. For this reason I always lace as shown in first photo. It seems like most of the photos I see here choose the opposite from me. I'm aware of the argument suggesting the outside spokes can bow out and intercept the derailer but have only seen one case of that --and those spokes had been allowed to get way too loose. I have seen dozens of cases of the chain destruction however.
