I have a pair of Zonda's, and absolutely hate the fact that you need special tools to true them. I brought them to a bike shop and they broke two spokes and blamed it on me and said the wheels were shot. The had a nice new set of MAVICs at 250 euro's though - but naturally I didn't jump on that. Bumholes. I build a set of campy 36 spoke hubs in a low cost, yet utterly bomb-proof and self-maintainable set instead.
