Thats awesome to hear!
We were a bit unsure about it as its always a bit daunting going to a new resort when you have no idea how good the runs are going to be. But I'm happy to hear that its geared towards more advanced skiiers. We love a challenge!
It took us ages to try and find us somewhere good to stay there as well as every website recommended different ski chalets. Absolute nightmare!
We ended up booking with this company in the end though: http://www.casamundo.co.uk/ so hopefully it works out okay.
Will let you know what I think of mad river when I get back!
