Switch to Sram XG-1190. Quiet, light. Excellent cassette and better made than the DuraAce 11spd. Not cheap for sure. But Im totally satisfied. Run 9070 Di2 BTW and a CN9000 chain.

The one with the 3 large sprockets on a 4 arm spider, sure I saw a good few of them folded up. They went to 5 arm shortly after.

I'm running XT cassette and KMC chain on my tandem with zero failures (over 12,000 miles). I've also used older Dura Ace cassettes on a tandem with no issues. I would not dare put a 9000 cassette on my tandem.
This has happened on the XT CS-771-10 11-32 as well. I've seen a few other photos of breaks in the same way around the rivet.

I don't think that swapping to an ultegra with heavier materials and overall weight is a solution.
Shimano needs to get this one sorted out. Looks like they went the cheap route on the cassette to get it lighter instead of milling it out of an entire piece, to include the hub connection point, they went with a carbon/rivet setup...kind of silly. Really don't want carbon on the exact point where all torque is connected/translated into wheel turning and the axle in my world anyway.
Only downside to the SRAM XG1190, is the price, $350+ even on the Bay...but the weight/durability and performance are hard to argue with on the other hand.
