I bought an old/er set of wheels with Campy hubs and rims and Ti spokes. Was really light. Broke a spoke on my first ride after tweaking all of them. Broke 2 more on the 3rd ride.
These are the only 3 spokes I've ever popped.
Relaced the wheels with some new standard wheelsmith DB spokes - they may weigh a few grams more but I haven't had a problem since.
