In reply to Swampi:
We spent 6 days in the Silvretta over Easter, finishing on the 29th and there was good snow coverage all around the tour - ski's on all the way down to Wirl at the end. Conditions were mostly very good once out of the resort on the first day with mostly great powder descents and the odd bit of crust/porridge/sastrugi here and there as you would expect, but nothing too bad.
