Also check out the thread "Zonda wheels" (Campy's model name), which I think is in the Campy sub-forum.
Near-universal positive reports in that thread.
As you may know, Fulcrum brand is owned by Campy and there is very close correspondence between most Fulcrum and Campy models. Rims are identical, hubs nearly identical, and typically the only difference is graphics and the presence/absence of the rear wheel "G3" spoke lacing pattern.
Few months ago I damaged a Shamal Ultra wheel set in a race crash. Decided to replace with Zonda, the 5-6 oz lighter weight of Shamal wheels was no way worth an extra $600+ for me.
IIRC, I paid about $350 for the Zonda wheelset from Wiggle, free shipping and no duty tax was assessed (very rare to get charged).
Be sure to apply Wiggle discount codes for extra savings. I think right now, codes 10-EXTRA and/or 12-EXTRA are both working.
