Did the marketing department of some bike-manufacturer get you? A good 32-spoke wheel is strong and stays true. The weight-savings on 8 spokes is less than your breakfast. By far. I'd go with the build using 32 spokes. They are, after all, the most commonly used wheels for serious purposes - such as riding a bicycle for recreation and pleasure and touring.

I rue the day the manufacturers decided to cut costs by having their marketing departments try to convince everyone out there that we need as few spokes as possible. A 18-spoke radial front wheel is fine if your racing, especially on a track, but it really has no business on a bike someone rides in the countryside on the weekends. Same for low-count wheels with 20, 22, 24, etc spokes. All it really does is allows the bike-manufacturers to see greater profits. While making trips to the bike-shop a more commonplace event. For repairs - not to buy a new component.
