The R-Sys failures were all on the v1.0 of the wheelset. I've seen the new v2.0 wheels. Watched in person as a mechanic laid the wheel on its side, and jumped on the spokes. I haven't heard any horror stories of these newer ones. I'd be tempted myself, but they're not as aero or light as others, and as with most things Mavic, they're overpriced. You can get comparable, even better items, elsewhere for less.
