I'm assuming the reasoning behind not using Revolution spokes is that the disc puts more stress on the spokes and 14/15ga spokes would be more likely to break over time from the extra torque? The wheels I've been eyeballing have 14/15ga spokes, but I only weigh 130 lbs so I would guess that I could probably get away with butted spokes and not really have as much trouble as a larger rider. It doesn't say whether it has aluminum or brass nipples. I never thought of the nipples as that big of a deal. Is this something I should even make an issue about when I order the wheels?
