Wombat is right. In summary: Great snow up top, but if you want to ski lower down bring your rock skis and mogul knees.
I went on Sunday - In contrast to last time there were no queues to get a ticket, then I spent the morning on the top pistes by the ice flyer on very nice pistes, with full snow cover. Weather was also great, just below zero at the top and sunshine over the fog which was sitting in the valleys at about 1500m. Pistes were all quite busy with a couple of minutes queue for each lift.
Then after lunch we went down Rotegg. It was tough, by far the hardest descent I've done (only started skiing last year, so I'm not exactly a freeride pro). Steep, big, rough moguls and a mix of hard and soft snow where the sun had reached it. A few of the scraped soft bits had rocks just underneath which made some expensive noises.
The lower pistes were significantly warmer then up top and by afternoon were already cut up, with rocks poking through every so often, so we rode down some of the bowls beside the piste. Most were nice and fluffy if a bit lumpy. One of the bowls between the lower traverse piste and the main red run had 3cm crust then soft sticky snow underneath. I faceplanted half way down, luckily avoiding rocks, and then spent at least 10 minutes retrieving my ski and trying to get the snow out of the binding.
The piste down to Trubsee was officially closed, but we went down anyway at the end of the day. It was also a bit scraped up, but with avoidable mud in a few places rather than sharp stones underneath.
Overall it was a great day, but my skis now need a full service to regrind the edges and fill big gouges in the base
I was surprised that they hadn't put artificial snow on the pistes. There appeared to have been zero artificial snowmaking, despite the lower pistes all being fully equipped for it. I guess they are trying to save their money in case a hot spell comes and it all melts. Given the price of the lift ticket I'm not impressed.
